allwinner: Move SEPARATE_NOBITS_REGION to platforms

For the existing SoCs we support, we use SEPARATE_NOBITS_REGION, to move
some parts of the data into separate memory regions (to save on the SRAM
A2 we are loaded into).
For the upcoming H616 platform this is of no concern (we run in DRAM),
so make this flag a platform choice instead.

allwinner: Build PMIC bus drivers only in BL31

These are used by the PMIC setup code, which runs during BL31
initialization, and the PSCI shutdown code, also a part of BL31.
They can't be needed before BL31, or it wouldn't be possible to boot.
Allwinner platforms don't generally build anything but BL31 anyway, but
this change improves clarity and consistency with allwinner-common.mk.

allwinner: Unify platform.mk files

For the two different platforms we support in the Allwinner port we
mostly rely on header files covering the differences. This leads to the
platform.mk files in the respective directories to be almost identical.

To avoid further divergence and make sure that one platform doesn't
break accidentally, let's create a shared allwinner-common.mk file and
include that from the platform directory.

drivers: i2c: mentor: move platform code into header files

At the moment we have two I2C stub drivers (for the Allwinner and the
Marvell platform), which #include the actual .c driver file.
Change this into the more usual design, by renaming and moving the stub
drivers into platform specific header files and including these from the
actual driver file. The platform specific include directories make sure
the driver picks up the right header automatically.

allwinner: Add Allwinner H6 SoC support

The H6 is Allwinner's most recent SoC. It shares most peripherals with the
other ARMv8 Allwinner SoCs (A64/H5), but has a completely different memory
map.

Introduce a separate platform target, which includes a different header
file to cater for the address differences. Also add the new build target
to the documentation.

The new ATF platform name is "sun50i_h6".
