allwinner: H616: Add reserved-memory node to DT

When the BL31 for the Allwinner H616 runs in DRAM, we need to make sure
we tell the non-secure world about the memory region it uses.

Add a reserved-memory node to the DT, which covers the area that BL31
could occupy. The "no-map" property will prevent OSes from mapping
the area, so there would be no speculative accesses.

plat: ti: k3: board: Let explicitly map our SEC_SRAM_BASE to 0x0

ENABLE_PIE (position independent executable) is default on K3
platform to handle variant RAM configurations in the system. This,
unfortunately does cause confusion while reading the code, so, lets
make things explicit by selecting 0x0 as the "SEC_SRAM_BASE" out of
which we compute the BL31_BASE depending on usage.

Lets also document a warning while at it to help folks copying code
over to a custom K3 platform and optimizing size by disabling PIE to
modify the defaults.

plat: ti: k3: platform_def.h: Define the correct number of max table entries

Since we are using static xlat tables, we need to account for exact
count of table entries we are actually using.
peripherals usart, gic, gtc, sec_proxy_rt, scfg and data account for 6 entries
and are constant, however, we also need to account for:
bl31 full range, codebase, ro_data as additional 3 region

With USE_COHERENT_MEM we do add in 1 extra region as well.

This implies that we will have upto 9 or 10 regions based on
USE_COHERENT_MEM usage. Vs we currently define 8 regions.

This gets exposed with DEBUG=1 and assert checks trigger, which for some
reason completely escaped testing previously.

allwinner: Add Allwinner H616 SoC support

The new Allwinner H616 SoC lacks the management controller and the secure
SRAM A2, so we need to tweak the memory map quite substantially:
We run BL31 in DRAM. Since the DRAM starts at 1GB, we cannot use our
compressed virtual address space (max 256MB) anymore, so we revert to
the full 32bit VA space and use a flat mapping throughout all of it.

The missing controller also means we need to always use the native PSCI
ops, using the CPUIDLE hardware, as SCPI and suspend depend on the ARISC.

The code to power the current core off when SCPI is not available is now

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.
