[Why]
Some LED panel drivers might not like fractional PWM. In such cases,
backlight flickering may be observed.
[How]
Add a DC feature mask to disable fractional PWM, and associate it with
the preexisting dc_config flag.
The flag is only plumbed through the dmcu firmware, so plumb it through
the driver path as well.
To disable, add the following to the linux cmdline:
amdgpu.dcfeaturemask=0x4

[Why]
Adding psr mask to dc features allows selectively disable/enable psr.
Current psr implementation may not work with non-pageflipping application.
Until resolved it should be disabled by default.
[How]
Add dcfeaturemask for psr enablement. Disable by default.
To enable set amdgpu.dcfeaturemask=0x8 in grub kernel command line.

get_atc_vmid_pasid_mapping_valid() is very similar to
get_atc_vmid_pasid_mapping_pasid(), so they can be merged into a new
function get_atc_vmid_pasid_mapping_info() to reduce register access
times. More importantly, getting the PASID and the valid bit atomically
with a single read fixes some potential race conditions where the
mapping changes between the two reads.
