memory: pl172: correct MPMC peripheral ID register bits



According to PL172 TRM read of bits [7:6] of MPMCPeriphID3 is
undefined, so unmask them. Also the driver supports all currently
present revisions of PL172, this allows to alleviate requirements to
the revision version matched by the driver.
