ArmVirtPkg/FdtPciPcdProducerLib: eliminate unchecked PcdSetXX() calls 

These are deprecated / disabled under the
DISABLE_NEW_DEPRECATED_INTERFACES feature test macro.

Introduce a variable called PcdStatus, and use it to assert the success of
these operations (there is no reason for them to fail here).
