[PATCH v3 5/9] ArmVirtPkg/ArmVirtQemu: add ResetSystem PEIM for upcoming TPM2 support


Ard Biesheuvel
 

As a first step in gradually adding TPM2 support to ArmVirtQemu, add
the TPM2_ENABLE configurable to the [Defines] section, and if it is
set, add the ResetSystem PEIM to the build, along with the library
class references that we will need to support it:
- wire ArmVirtPsciResetSystemPeiLib into the ResetSystem PEIM itself,
which will be in charge of performing the actual reset
- add PeiResetSystemLib as the common ResetSystemLib resolution for
PEIM class modules, so that other PEIMs will invoke the PPI
published by the ResetSystem PEIM.
