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.
