Move all the platform data to devicetree.
The only bit dropped is the PWM beeper, which requires the PWM driver
to be updated. I figured it's okay to remove it here since it's really
a non-critical device, and it'll be re-introduced soon enough.
The other change is the CS line of the SPI is now set as active low. The
SPI core would have forced "active low" anyway, unless the 'spi-cs-high'
property is set.
In the process of moving to devicetree, we also switched to new drivers:
- We use the simple-audio-card and simple-amplifier drivers instead of
the custom ASoC code;
- We use the new Ingenic DRM driver coupled with the GiantPlus GPM940B0
DRM panel driver instead of the old framebuffer driver;
- We use the new jz4780-dma driver instead of the old jz4740-dma one;
- We use the ingenic-nand and jz4740-ecc drivers instead of the old
jz4740-nand driver;
- We use ingenic-battery instead of jz4740-battery;
- We use iio-hwmon instead of jz4740-hwmon;
- We use ingenic-iio instead of the old jz4740-adc MFD driver.

calc_vmlinuz_load_addr.c requires SZ_64K to be defined for alignment
purposes. It included "../../../../include/linux/sizes.h" to define
that size, however "sizes.h" tries to include <linux/const.h> which
assumes linux system headers. These may not exist eg. the following
error was encountered when building Linux for OpenWrt under macOS:
In file included from arch/mips/boot/compressed/calc_vmlinuz_load_addr.c:16:
arch/mips/boot/compressed/../../../../include/linux/sizes.h:11:10: fatal error: 'linux/const.h' file not found
^~~~~~~~~~
Change makefile to force building on local linux headers instead of
system headers. Also change eye-watering relative reference in include
file spec.

DTC introduced an i2c_bus_reg check in v1.4.7, used since Linux v4.20,
which complains about upper case addresses used in the unit name.
nexys4ddr.dts names an I2C device node "ad7420@4B", leading to:
arch/mips/boot/dts/xilfpga/nexys4ddr.dts:109.16-112.8: Warning
(i2c_bus_reg): /i2c@10A00000/ad7420@4B: I2C bus unit address format

In Kbuild, if_changed and friends must have FORCE as a prerequisite.
Hence, $(filter-out FORCE,$^) or $(filter-out $(PHONY),$^) is a common
idiom to get the names of all the prerequisites except phony targets.
Add real-prereqs as a shorthand.
Note:
We cannot replace $(filter %.o,$^) in cmd_link_multi-m because $^ may
include auto-generated dependencies from the .*.cmd file when a single
object module is changed into a multi object module. Refer to commit
69ea912fda74 ("kbuild: remove unneeded link_multi_deps"). I added some
comment to avoid accidental breakage.

According to the Schematic, the hardware of ci20 leads to uart3,
but not to uart2. Uart2 is miswritten in the original code.

Remove the Malta display platform code in favour of probing the
img-ascii-lcd driver via device tree. This reduces the amount of
platform code & the img-ascii-lcd driver offers us advantages in terms
of code sharing with other boards & functionality such as changing the
displayed message via sysfs. Defconfigs are untouched because the driver
already defaults y on when CONFIG_MIPS_MALTA=y.

KEXEC needs the new kernel's load address to be aligned on a page
boundary (see sanity_check_segment_list()), but on MIPS the default
vmlinuz load address is only explicitly aligned to 16 bytes.
Since the largest PAGE_SIZE supported by MIPS kernels is 64KB, increase
the alignment calculated by calc_vmlinuz_load_addr to 64KB.

The Intel EG20T Platform Controller Hub used on the MIPS Boston
development board supports prefetching memory to optimize DMA transfers.
Unfortunately for unknown reasons this doesn't work well with some MIPS
CPUs such as the P6600, particularly when using an I/O Coherence Unit
(IOCU) to provide cache-coherent DMA. In these systems it is common for
DMA data to be lost, resulting in broken access to EG20T devices such as
the MMC or SATA controllers.
Support for a DT property to configure the prefetching was added a while
back by commit 549ce8f134bd ("misc: pch_phub: Read prefetch value from
device tree if passed") but we never added the DT snippet to make use of
it. Add that now in order to disable the prefetching & fix DMA on the
affected systems.

The Ocelot PCB120 evaluation board is different from the PCB123 in that
it has 4 external VSC8584 (or VSC8574) PHYs.
It uses the SoC's second MDIO bus for external PHYs which have a
reversed address on the bus (i.e. PHY4 is on address 3, PHY5 is on
address 2, PHY6 on 1 and PHY7 on 0).
Here is how the PHYs are connected to the switch ports:
port 0: phy0 (internal)
port 1: phy1 (internal)
port 2: phy2 (internal)
port 3: phy3 (internal)
port 4: phy7
port 5: phy4
port 6: phy6
port 9: phy5
