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.

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.
