Addressed some more review comments - thank you Alex and Richard for the reviews.

Changes in v3:
- Patch 2&3 (was 2):
  - Split patch 2 into 2 parts, one enabling FNG1, FNG0, and A2, and another
    enabling ASID2 for cpu_max. The patch enabling cpu_max can be dropped or
    reverted later if not desired at this time.
- Patch 4 (was 3):
  - Check for presence of TCR2_EL1 in test, abort test if not present.
  - Additionally test that new fields read as RES0 if ASID2 is not present.

Changes in v2:
- patch 2:
  - Added FNG1, FNG0, A2 to mask for tcr2_el2_write
- patch 3:
  - Changed test for ASID from "=0x100" to "!= 0"
