As per the current code base, PM_CLOCK_SETRATE and PM_CLOCK_GETRATE
APIs are not supported for the runtime operations in the firmware and
the TF-A it is already returning an error when there is any request
to access these APIs. So, just removing the unused code to avoid the
confusion around these APIs.
Also, there is no issue with the backward compatibility as these APIs
were never used since implemented. Hence no need to bump up the
version of the feature check API as well.

Switch from IMX_BOOT_UART_BASE=0 to IMX_BOOT_UART_BASE=auto to make it
more obvious that the detection is based on the runtime autodetection.
In addition this moves the evaluation of IMX_BOOT_UART_BASE into the
makefile which removes the ugly conditional compilation as well.

* changes:
feat(rdn2): enable Neoverse N2 CPU error handling support
feat(sgi): firmware first error handling for Neoverse N2 CPU
feat(arm): enable FHI PPI interrupt to report CPU errors
RD-N2 platform variants have Neoverse N2 CPU that supports RAS
extensions. N2 CPU has error node that captures the faults occurring on
L1, L2 tag and data RAMs. This node captures the error information in
its error records and generates fault handling interrupt on error event.
This patch adds reference implementation to demonstrate firmware-first
error handling of 1-bit CE that occur on CPU. On error event the error
handler reads the error records and ELx context information and forwards
it to secure partition. Secure partition creates a CPER record from this
error information. Finally the handler notifies the OS about the RAS
error using the SDEI notification mechanism.

To handle the core corrected errors in the firmware, the FHI PPI
interrupt has to be enabled on all the cores. At boot, when the RAS
framework is initialized, only primary core is up and hence core FHI PPI
interrupt is enabled only on primary core. This patch adds support to
configure and enable core FHI interrupt for all the secondary cores as
part of their boot sequence.

On systems with SCP (running crust) scpi_system_reboot action
performs board-level (PMIC) reboot. This doesn't preserve RAM content
on A64 PinePhone at least.
warm/soft system reset without RAM reset is required to get
pstore (persistent storage) in RAM working with Linux kernel. That is
very useful for oops/panic logging for post mortem analysis.
scpi_system_reset action performs reset via SoC reset (using watchdog)
and RAM content is preserved in this case. Linux kernel detects
system_reset2 support and uses it for warm reset automatically.

This involves replacing:
* the reset_func with the standard cpu_reset_func_{start,end} to apply
errata automatically
* the <cpu>_errata_report with the errata_report_shim to report errata
automatically
...and for each erratum:
* the prologue with the workaround_<type>_start to do the checks and
framework registration automatically
* the epilogue with the workaround_<type>_end
* the checker function with the check_erratum_<type> to make it more
descriptive
It is important to note that the errata workaround sequences remain
unchanged and preserve their git blame.
Testing was conducted by:
* Building for release with all errata flags enabled and running
script in change 19136 to compare output of objdump for each errata.
* Testing via script was not complete, as it directed to verify the
check and the workaround functions of few erratas manually.
* Manual comparison of disassembly of converted functions with non-
converted functions

vs
aarch64-none-elf-objdump -D <trusted-firmware-a clean repo>/build/fvp/release/bl31/bl31.elf
* Manual comparison of disassembly of both both files(bl31.elf)
ensured,the ported changes were identical and hence verified.
* Build for release with all errata flags enabled and run default tftf
tests.
