allwinner: Move sunxi_cpu_power_off_self() into platforms
The code to power the current core off when SCPI is not available is now
different for the two supported SoC families.
To make adding new platforms easier, move sunxi_cpu_power_off_self()
into the SoC directory, so we don't need to carry definitions for both
methods for all SoCs.
On the H6 we just need to trigger the CPUIDLE hardware, so can get rid
of all the code to program the ARISC, which is now only needed for the
A64 version.

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.

This gives the rich OS the flexibility to choose between I2C and RSB

The H6 has a "secure port controller" similar to the A64/H5, but with
more ports and a different register layout. Split the platform-specific
parts out into a header, and add the missing MMIO base address.

allwinner: Convert AXP803 regulator setup code into a driver
Previously, the A64/H5 and H6 platforms' PMIC setup code was entirely
independent. However, some H6 boards also need early regulator setup.
Most of the register interface and all of the device tree traversal code
can be reused between the AXP803 and AXP805. The main difference is the
hardware bus interface, so that part is left to the platforms. The
remainder is moved into a driver.
I factored out the bits that were obviously specific to the AXP803;
additional changes for compatibility with other PMICs can be made as
needed.
The only functional change is that rsb_init() now checks the PMIC's chip
ID register against the expected value. This was already being done in
the H6 version of the code.

allwinner: a64: power: Remove obsolete register check
As of a561e41bf1d2 ("allwinner: power: add enable switches for DCDC1/5")
there are no longer regulators without an enable register provided.
Since it seems reasonable that this will continue to be the case, drop
the check.

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.

- Check the return value from sunxi_init_platform_r_twi().
- Print the PMIC banner before doing anything that might fail.
- Remove double prefixes in error messages.
- Consistently omit the trailing period.
- No need to print the unknown SoC's ID, since we already did that
earlier in bl31_platform_setup().
- On the other hand, do print the ID of the unknown PMIC.
- Try to keep the messages concise, as the large string size in these
files was causing the firmware to spill into the next page.
- Downgrade the banner from NOTICE to INFO. It's purely informational,
and people should be using debug builds on untested hardware anyway.
