powerpc: Add HAVE_PERF_USER_STACK_DUMP support
With perf regs support enabled for powerpc, in commit ed4a4ef85cf5 ("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.
