[LOCAL] arm64: perf: Report arm pc registers for compat perf
If perf is built as arm 32-bit, it only reads 15 registers as arm
32-bit register map and this breaks dwarf call-chain in compat
perf because pc register information is not filled.
Report arm pc registers for 32-bit compat perf.
Without this, arm 32-bit perf dwarf call-graph shows below
verbose message:
unwind: reg 15, val 0
unwind: reg 13, val
ffbc6360
unwind: no map for 0
