Ilias Apalodimas 1262c02677 MdeModulePkg/VariableStandaloneMm: Set PcdFlashNvStorageVariableBase to Pcd ... Instead of running StMM in SPM, OP-TEE creates a new secure partition, which emulates SPM and isolates StMM from the rest of the Trusted Applications (TAs). We can then compile StMM as an FD image and run it in OP-TEE. With the addition of a new RPMB driver, we can leverage OP-TEE and store variables to an RPMB device. Since EDK2 upper layers expect byte addressable code, for the RPMB to work, we need to allocate memory and sync it with the hardware on read/writes. Since DynamicPCDs are not supported in that context we can only use PatchablePCDs. So let's switch them to Pcd instead of FixedPcd and accomodate the new driver. While at it, move the rest of the variables under Pcd section, instead of FixedPcd -- this is in line with how the variables are defined in the other Variable modules.
