Log Message:
-----------
MdeModulePkg/Library: make ArmFfaPeiLib available early PEIM stage
commit 26fb5edff397
("MdeModulePkg/ArmFfaLib: Add depex on gEfiPeiMemoryDiscoveredPpiGuid")
restricts ArmFfaPeiLib usage only after PEI phase can be used
permanent memory. However, This would be problem for PEIM
which runs before gEfiPeiMemoryDiscoveredPpiGuid Ppi installed.
(i.e) Tcg2Pei PEIM.
To resolve this, remove dependency on gEfiPeiMemoryDiscoveredPpiGuid
and let ArmFfaPeiLib remap the Rx/Tx buffer after
gEfiPeiMemoryDiscoveredPpiGuid is installed so that ArmFfaPeiLib can be
used with temporary memory.
