allwinner: Export sunxi_private.h
So far we have a sunxi_private.h header file in the common code directory.
This holds the prototypes of various functions we share in *common*
code. However we will need some of those in the platform specific code
parts as well, and want to introduce new functions shared across the
whole platform port.
So move the sunxi_private.h file into the common/include directory, so
that it becomes visible to all parts of the platform code.
Fix up the existing #includes and add missing ones, also add the
sunxi_read_soc_id() prototype here.
This will be used in follow up patches.

allwinner: H6: Fix SRAM size
The SRAM in the Allwinner H6 SoC starts at 0x2000, with the last part
ending at 0x117fff (although with gaps in between).
So SUNXI_SRAM_SIZE should be 0xf8000, not 0x980

Fix this to map the arisc exception vector area, which we will need
shortly.

allwinner: Adjust memory mapping to fit into 256MB
At the moment we map as much of the DRAM into EL3 as possible, however
we actually don't use it. The only exception is the secure DRAM for
BL32 (if that is configured).
To decrease the memory footprint of ATF, we save on some page tables by
reducing the memory mapping to the actually required regions: SRAM, device
MMIO, secure DRAM and U-Boot (to be used later).
This introduces a non-identity mapping for the DRAM regions.

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: sun50i_h6: initialise I2C just before powering down

allwinner: sun50i_h6: initialise I2C just before powering down
Even though we initialise the platform part and the I2C controller
itself at boot time, we actually only access the bus on power down.
Meanwhile a rich OS might have configured the I2C pins differently or
even disabled the controller.
So repeat the platform setup and controller initialisation just before
we actually access the bus to power off the system. This is safe,
because at this point the rich OS should no longer be running.

allwinner: implement system power down on H6 w/ AXP805
The AXP805 PMIC used with H6 is capable of shutting down the system.
Add support for using it to shut down the system power.
The original placeholder power off code is moved to A64 code, as it's
still TODO to implement PMIC operations for A64.
