arm64: Use Signed/Unsigned enums for TGRAN{4,16,64} and VARange
Open-coding the feature matching parameters for LVA/LVA2 leads to
issues with upcoming changes to the cpufeature code.
By making TGRAN{4,16,64} and VARange signed/unsigned as per the
architecture, we can use the existing macros, making the feature
match robust against those changes.
