moduleparams: Add hexint type parameter
For bitmasks printing values in hex is more convenient.
Prefix with `0x` to make it clear, that it’s a hex value, and pad it
out.
Using the helper for `amdgpu.ppfeaturemask`, it will look like below.
Before:
$ more /sys/module/amdgpu/parameters/ppfeaturemask
4294950911
After:
$ more /sys/module/amdgpu/parameters/ppfeaturemask
0xffffbfff
