Subject: [PATCH v3 22/26] KVM: SVM: Use BIT() and GENMASK() for definitions in svm.h

Use BIT() and GENMASK() (and *_ULL() variants) to define the bitmasks in
svm.h.

Opportunistically switch the definitions of AVIC_ENABLE_{SHIFT/MASK}
and X2APIC_MODE_{SHIFT/MASK}, as well as SVM_EVTINJ_VALID and
SVM_EVTINJ_VALID_ERR, such that the bitmasks are defined in the correct
order.

No functional change intended.
