ams_enable_channel_sequence constructs a "scan_mask" for all the PS and
PL channels. This works out fine, since scan_index for these channels is
less than 64. However, it also includes the ams_ctrl_channels, where
scan_index is greater than 64, triggering undefined behavior. Since we
don't need these channels anyway, just exclude them.

ad7380x(-4) parts are able to do oversampling to increase accuracy.
This chips supports a normal oversampling mode and a rolling mode and
also allows enabling and disabling extra resolution bits when
oversampling is enabled.
We have intentionally left out the rolling mode for now as there is not
a compelling use case for it. User can process a captured data buffer
to get the same effect.
We are also currently not supporting changing the oversampling mode
independently of the resolution bits. The resolution boost feature
can only be enabled when oversampling is enabled and oversampling is
not as useful without the resolution boost. So for now we consider the
features tightly coupled. When oversampling is enabled, the resolution
boost is enabled and when oversampling is disabled, the resolution
boost is disabled.
Since the resolution boost feature causes 16-bit chips to now have
18-bit data which means the storagebits has to change from 16 to 32
bits, we use the new ext_scan_type feature to allow changing the
scan_type at runtime based on if the resolution boost is enabled or
not.
SPI message optimization has to be moved since now some of the xfer
parameters change based on the resolution boost mode.
A few neighboring comments are also fixed up while we are touching this
code.

This changes the AD7380 to use spi_optimize_message() to optimize
buffered reads.
This changes both direct reads and buffered reads to use the same
spi_message. This has some (welcome) side effects. The first is that
in buffered reads, the timestamp will now correspond to the same sample
rather than the previous sample. The second is that direct reads now
use the same SPI bus speed as buffered reads.
This reduces CPU usage of the IRQ thread from around 25% to around 20%
when sampling at 10 kHz on a ZedBoard.

The current driver supports only parts with 2 channels.
In order to prepare the support of new compatible ADCs with more
channels, this commit:
- defines MAX_NUM_CHANNEL to specify the maximum number of
channels currently supported by the driver
- adds available_scan_mask member in ad7380_chip_info structure
- fixes spi xfer struct len depending on number of channels
- fixes scan_data.raw buffer size to handle more channels
- adds a timing specifications structure in ad7380_chip_info structure

The driver currently implements basic support for the AD7380, AD7381,

as well as additional features of the chip will be added in future patches.

When enabling the core, make sure DRP (Dynamic Reconfiguration Port)
is locked. Most of the designs don't really use it but we still get the
lock bit set. So let's do it all the time so the code is generic.
While at it reduce the timeout time to 1 microsecond as it seems to be
enough and goes in line with what we have on the similar DAC core
(adi-axi-dac).

Make sure we use a DMA safe buffer (IIO_DMA_MINALIGN) for all the spi
transfers. Only relevant for writes since for reads
spi_write_then_read() is used which does not require DMA safe buffers.

This patch fixes two issues regarding the sampling frequency setting:
-The attribute was set as per device, not per channel. As such, when
setting the sampling frequency, the configuration was always done for
the slot 0, and the correct configuration was applied on the next
channel configuration call by the LRU mechanism.
-The LRU implementation does not take into account external settings of
the slot registers. When setting the sampling frequency directly to a
slot register in write_raw(), there is no guarantee that other channels
were not also using that slot and now incorrectly retain their config
as live.
Set the sampling frequency attribute as separate in the channel templates.
Do not set the sampling directly to the slot register in write_raw(),
just mark the config as not live and let the LRU mechanism handle it.
As the reg variable is no longer used, remove it.

To make sure that we have the best timings on the serial data interface
we should calibrate it. This means going through the device supported
values and see for which ones we get a successful result. To do that, we
use a prbs test pattern both in the IIO backend and in the frontend
devices. Then for each of the test points we see if there are any
errors. Note that the backend is responsible to look for those errors.
As calibrating the interface also requires that the data format is disabled
(the one thing being done in ad9467_setup()), ad9467_setup() was removed
and configuring the data fomat is now part of the calibration process.
