With the introduction of FEAT_LPA2, the Arm ARM adds a new level of translation, level -1, so levels can now be in the range [-1;3]. 3 is always the last level and the first level is determined based on the number of VA bits in use. Convert level variables to use a signed type in preparation for supporting this new level -1. Since the last level is always anchored at 3, and the first level varies to suit the number of VA/IPA bits, take the opportunity to replace KVM_PGTABLE_MAX_LEVELS with the 2 macros KVM_PGTABLE_FIRST_LEVEL and KVM_PGTABLE_LAST_LEVEL. This removes the assumption from the code that levels run from 0 to KVM_PGTABLE_MAX_LEVELS - 1, which will soon no longer be true. No behavioral changes intended.
