powerpc: Add HAVE_PERF_USER_STACK_DUMP support



With perf regs support enabled for powerpc, in commit ed4a4ef8
("powerpc/perf: Add support for sampling interrupt register state"),
the support for obtaining perf user stack dump is already enabled. This
patch declares the support for same and also updates documentation to
mark the support for perf-regs and perf-stackdump.
