Subject: [PATCH 2/2] drm/amdgpu: Change type of module param `ppfeaturemask` to hex

The newly added hex helper is more convenient for bitmasks.

Before:

    $ more /sys/module/amdgpu/parameters/ppfeaturemask
    4294950911

After:

    $ more /sys/module/amdgpu/parameters/ppfeaturemask
    0xffffbfff
