The UEFI 2.9A errata makes clear how ARM processor type encoding should be done: it is meant to be equal to Generic processor, using a bitmask. The current code assumes, for both generic and ARM processor types that this is an integer, which is an incorrect assumption. Fix it. While here, also fix a compilation issue when using W=1.
