feat(spmd): add spmd logical partitions

Add header file to help with creation of SPMD logical partitions. Also
update linker files to create sections to record SPMD logical partitions
declared. This follows the same pattern as the EL3 SPMC's logical
partitions. This patch also adds initialization of SPMD logical
partitions when the SPMD comes up.
ENABLE_SPMD_LP is a build flag that is used to enable support for
SPMD logical partitions.
Note that the approach chosen is to keep SPMD and SPMC logical
partition support separate, as opposed to extend the existing SPMC
logical partition support since the code would need to have a number of
ifdefs and the interactions with various build options such as
SPMC_AT_EL3 needs to be accounted for, which would make code more
complicated.

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.

HFG*_EL2 registers control the fine-grained traps introduced by

of this feature can be trapped to EL3, not being able to handle the
trap correctly. This patch disables all fine-grained traps by default
to prevent such unexpected behavior.

feat(sgi): firmware first error handling for Neoverse N2 CPU

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.

feat(arm): enable FHI PPI interrupt to report CPU errors

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.

fix(zynqmp): resolve runtime error in TSP

TSP(bl32) requires secure interrupts to be handled at S-EL1.
Enable the ZynqMP to handle secure interrupts in S-EL1 by setting
GICV2_G0_FOR_EL3 to 0 in case of SPD=tspd build option.

For ZYNQMP_WDT_RESTART build option GICV2_G0_FOR_EL3 needs to be
enabled and thus for ZynqMP GICV2_G0_FOR_EL3 is set to 1 by default.
On GICv2, when GICV2_G0_FOR_EL3 is set to 1, Group 0 interrupts
target EL3. This allows GICv2 platforms to enable features requiring
EL3 interrupt type.

This also means that all GICv2 Group 0 interrupts are delivered
to EL3, and the Secure Payload interrupts needs to be synchronously
handed over to Secure EL1 for handling.
