perf arm_spe: Decode ASE and FP fields in other operation
Add a check for other operation, which prevents any incorrectly
classifying. Parse the ASE and FP fields.
After:
. 0000002f: 48 06 OTHER ASE FP INSN-OTHER
. 00000031: b2 08 80 48 01 08 00 ff ff VA 0xffff000801488008
. 0000003a: 9a 00 00 LAT 0 XLAT
. 0000003d: 42 16 EV RETIRED L1D-ACCESS TLB-ACCESS
