Fix some violations to MISRA rule 8.3 ...

Wherever we use 'struct foo' and 'foo_t' interchangeably in a
function's declaration and definition, use 'struct foo' consistently
for both, as per the TF-A coding guidelines [1].

Remove .func and .endfunc assembler directives ...

These directives are only used when stabs debugging information
is used, but we use ELF which uses DWARF debugging information.
Clang assembler doesn't support these directives, and removing
them makes the code more compatible with clang.

Use ALIGN instead of NEXT in linker scripts ...

Clang linker doesn't support NEXT. As we are not using the MEMORY command
to define discontinuous memory for the output file in any of the linker
scripts, ALIGN and NEXT are equivalent.

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".

ti: k3: common: Enable interrupts before entering standby state ...

To wake a core from wfi interrupts must be enabled, in some cases they
may not be and so we can lock up here. Unconditionally enable interrupts
before wfi and then restore interrupt state.

allwinner: Detect and output current SoC ...

So far we already support booting on two different SoCs, and we will
shortly add a third, so add some code to determine the current SoC type.
This can be later used to runtime detect certain properties.

Also print the SoC name to the console, to give valuable debug information.

allwinner: security: Fix SPC guard ...

The "#ifdef SUNXI_SPC_BASE" guard was meant to allow the build on SoCs
without a Secure Peripherals Controller, so that we skip that part of
the security setup. But in the current position this will trigger a
warning about an unused variable.

Simply move the guard one line up to cover the variable as well.

Enable MMU without stack for xlat v2/DynamIQ

DynamIQ: Enable MMU without using stack ...

Having an active stack while enabling MMU has shown coherency problems.
This patch builds on top of translation library changes that introduces
MMU-enabling without using stacks.

Previously, with HW_ASSISTED_COHERENCY, data caches were disabled while
enabling MMU only because of active stack. Now that we can enable MMU
without using stack, we can enable both MMU and data caches at the same
time.

NOTE: Since this feature depends on using translation table library v2,
disallow using translation table library v1 with HW_ASSISTED_COHERENCY.

Fixes ARM-software/tf-issues#566
