fix(fvp): skip SP discovery through FFA_PARTITION_INFO_GET_REGS

The initialization function implemented for the dummy LSP of FVP port
invokes FFA_PARTITION_INFO_GET_REGS to obtain partition properties of
Secure Partitions managed by SPMC. This happens even before the normal
world is booted.

Hafnium SPMC mistakes this as a FF-A invocation from NWd. As per FF-A
version negotiation protocol, Hafnium locks the version of NWd to v1.3
whereas the NWd never got an opportunity to register its own framework
version.

This patch performs early exit from the helper utility to give NWd
endpoint/Hypervisor an opportunity to register its FF-A version with
SPM. We intentionally do not remove the helper utility as it will be
used in a different patchset for a new anticipated feature.

fix(cpufeat): extend FEAT_EBEP handling to delegate PMU control to EL2

Currently, the FEAT_EBEP feature presence check is only used for UNDEF
injection into lower ELs. However, this feature also affects the access
behavior of MDCR_EL2. Specifically, if the PMEE bits in MDCR_EL3 are not
set to 0b01, then the MDCR_EL2.PMEE bits cannot be configured by EL2.

This patch extends the use of FEAT_EBEP to delegate PMU IRQ and
profiling exception control to EL2 by setting MDCR_EL3.PMEE = 0b01.This
ensures that lower ELs can manage PMU configuration.

feat(cpufeat): enable FEAT_PFAR support

Implement support for FEAT_PFAR, which introduces the PFAR_ELx system
register, recording the faulting physical address for some aborts.
Those system registers are trapped by the SCR_EL3.PFARen bit, so set the
bit for the non-secure world context to allow OSes to use the feature.

This is controlled by the ENABLE_FEAT_PFAR build flag, which follows the
usual semantics of 2 meaning the feature being runtime detected.
Let the default for this flag be 0, but set it to 2 for the FVP.

The event log's DT bindings only specify the lower 32 bits of the event
log's size, but the size is held in a 64 bit variable on stack. When
conditions are right, the uninitialised upper 32 bits may contain
gibberish that throws off our computations, leading to faults.
