Jiping Ma c8c4b20395 arm64: perf: Report the PC value in REGS_ABI_32 mode 
commit 8dfe804a4031ca6ba3a3efb2048534249b64f3a5 upstream.

A 32-bit perf querying the registers of a compat task using REGS_ABI_32
will receive zeroes from w15, when it expects to find the PC.

Return the PC value for register dwarf register 15 when returning register
values for a compat task to perf.
