When pointer authentication is enabled, the LR value saved on the stack
contains a Pointer Authentication Code (PAC). It must be stripped to
retrieve the return address.

The PAC field is stored on the high bits of the address and defined as:
- PAC field = Xn[54:bottom_PAC_bit], when address tagging is used.
- PAC field = Xn[63:56, 54:bottom_PAC_bit], without address tagging.

With bottom_PAC_bit = 64 - TCR_ELx.TnSZ

The legacy console is gone. Re-add the console support based on the
multi-console framework.

I am still keeping the putc, getc, and flush callbacks in
uniphier_console.S to use plat/common/aarch64/crash_console_helpers.S

The console registration code already relies on that C environment
has been set up. So, I just filled the struct console fields with the
callback pointers, then called console_register() directly. I also
re-implemented the init function in C to improve the readability.

Removing the custom crash console implementation has one disadvantage;
we cannot use the crash console on very early crashes because
crash_console_helpers.S works only after the console is registered.
I can live with this limitation.

Tested on my boards, and confirmed this worked like before.

These errors are asynchronous and cannot be directly correlated with the
exact current running software, so handling them in the same EL is not
critical. Handling them in TF-A allows for more platform specific
decoding of the implementation defined exception registers

Neoverse N1 erratum 1275112 is a Cat B erratum [1],
present in older revisions of the Neoverse N1 processor core.
The workaround is to set a bit in the implementation defined
CPUACTLR_EL1 system register, which delays instruction fetch after
branch misprediction.

N1SDP platform supports RDIMMs with ECC capability. To use the ECC
capability, the entire DDR memory space has to be zeroed out before
enabling the ECC bits in DMC620. Zeroing out several gigabytes of
memory from SCP is quite time consuming so functions are added that
zeros out the DDR memory from application processor which is
much faster compared to SCP. BL33 binary cannot be copied to DDR memory
before enabling ECC so this is also done by TF-A from IOFPGA-DDR3
memory to main DDR4 memory after ECC is enabled.

Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which
the entire DDR space cannot be accessed as DRAM2 starts in base
0x8080000000. So these macros are redefined for all ARM platforms.
