arm64/cpufeature: Drop open encodings while extracting parange
Currently there are multiple instances of parange feature width mask open
encodings while fetching it's value. Even the width mask value (0x7) itself
is not accurate. It should be (0xf) per ID_AA64MMFR0_EL1.PARange[3:0] as in
ARM ARM (0487F.a). Replace them with cpuid_feature_extract_unsigned_field()
which can extract given standard feature (4 bits width i.e 0xf mask) field.
