ARM: oprofile: Fix backtraces in timer mode
Always allow backtraces when using oprofile on ARM, even if a PMU isn't present. Restores functionality originally introduced in commit 1b7b56982fdcd9d85effd76f3928cf5d6eb26155 ("oprofile: Always allow backtraces on ARM") by Richard Purdie. It is not that obvious, but there is now only one oprofile_arch_init() function. So the .backtrace callback is available also in timer mode. Implemented by removing code and using stubs for oprofile_perf_{init, exit} provided by <linux/oprofile.h>. This allows cleaning of other architecture specific implementations too.
