Currently perf_event.c is 64bit specific due to
inline assembly. Driver needs to support 32bit as well.
Move the assembly code to asm/perf_event.h so that
perf_event.c is 32/64 bit agnostic and move perf_event.c
to drivers/perf from 64bit-specific arch dir.

Since the files in the attachment directory are rarely used, remove
them. Update the data saved by this config option to work properly
with iommu groups.

[lmark@codeaurora.org: deadlock is not an issue on this branch
but this change is backported because there are security benefits
from removing the iommu debugfs attachments nodes, such as removing
register access.]

Add Writeable registers list for Digital codec and soundwire codec
regmap config to avoid invalid register access during reg_cache_sync.
Ensure digital codec clock is enabled before regcache sync to avoid
AHB access errors.Modify mutex use to avoid clock disabling during
regmap register access.
