OvmfPkg: replace PcdAcpiPmBaseAddress with PIIX4_PMBA_VALUE
In the next patches, we'll differentiate the PMBA IO port address that we
program on PIIX4 vs. Q35.
Normally we'd just turn PcdAcpiPmBaseAddress into a dynamic PCD. However,
because we need this value in BaseRomAcpiTimerLib too (which cannot access
RAM and dynamic PCDs), it must remain a build time constant. We will
introduce its Q35 counterpart later.
As first step, replace the PCD with a new macro in "OvmfPlatforms.h";
Jordan prefers the latter to fixed PCDs in this instance.
