Now that the driver core can properly handle constant struct bus_type,
move the greybus_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.

- Constify the of_phandle_args in xlate functions.
Driver changes:
- New interconnect driver for the MSM8909 platform.
- New interconnect driver for the SM7150 platform.
- Clean-up and removal of unused resources in drivers.
- Constify some pointers to structs.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The hard IRQ handler vsc_tp_irq() is called with a raw spinlock taken.
wake_up() acquires a spinlock, a sleeping lock on PREEMPT_RT. This leads
to sleeping in atomic context.
Move the wake_up() call to the threaded IRQ handler vsc_tp_thread_isr()
where it can be safely called.

MHI Host
========
- Added new MHI_PM_SYS_ERR_FAIL state to the MHI state machine to properly
cleanup the channel state if the device fails to respond to the MHI reset
during SYS_ERR handling. This issue was discovered with the Qualcomm AIC100 AI
accelerator device.
- Modified the code that reads and exposes the OEM_PK_HASH registers through
sysfs to read them on-demand instead of reading once during boot. Qualcomm
AIC100 devices support provisioning the keys dynamically, so this allows the
users to know the upto date information.
- Added tracepoint support to expose the debug information over tracefs.
- Reverted the commit that reads the MHI device revision from the device during
boot. This is done because the read info was not used anywhere (dead code) and
also it is not possible to read the revision info from all the devices.
- Constified the modem config for Telit FN980 modem as required by the MHI core.
MHI Endpoint
============
- Replaced kzalloc() with kcalloc() in an effort to avoid integer overflows
during multiplication. Even though there is no potential overflow in the
endpoint code, this is done for the sake of uniformity and best practice.
- Fixed the kmem_cache_create() failure check to use the correct variable.

Some of the registers on the SARADCv2 have bits write protected except
if another bit is set. This is usually done by having the lowest 16 bits
store the data to write and the highest 16 bits specify which of the 16
lowest bits should have their value written to the hardware block.
The write_enable mask for the channel selection was incorrect because it
was just the value shifted by 16 bits, which means it would only ever
write bits and never clear them. So e.g. if someone starts a conversion
on channel 5, the lowest 4 bits would be 0x5, then starts a conversion
on channel 0, it would still be 5.
Instead of shifting the value by 16 as the mask, let's use the OR'ing of
the appropriate masks shifted by 16.
Note that this is not an issue currently because the only SARADCv2
currently supported has a reset defined in its Device Tree, that reset
resets the SARADC controller before starting a conversion on a channel.
However, this reset is handled as optional by the probe function and
thus proper masking should be used in the event an SARADCv2 without a
reset ever makes it upstream.

The SARADCv2 on RK3588 (the only SoC currently supported that has an
SARADCv2) selects the channel through the channel_sel bitfield which is
the 4 lowest bits, therefore the mask should be GENMASK(3, 0) and not
GENMASK(15, 0).
