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.]

The current touch panel driver uses bit 5 in major hardware version to
decide panel used between 800S and 800H.
By setting the bit to 1 means 800S used while to 0 means 800H.

pm660_ldo10 supplies power for multiple consumers including UFS.
The load from UFS is invisible for the regulator before the driver
voted it. Any other light load consumers would vote its load and
force the regulator entering into LPM mode which cause OCP triggered.
Add proxy voter for pm660_ldo10 to track this existing UFS load.

Currently the interrupt trigger type is configured as NONE. This
causes a level handler to be assigned to these interrupts.
However, all of them are edge triggered interrupts with varying
falling/rising/both edge flavors. Update the device tree to
use their correct trigger types thereby preventing missed interrupt
storms because of incorrect handler types.
