Move the implementation of REG_GENMASK/REG_BIT to a more appropriate
place to be shared by i915, xe and possibly other parts of the kernel.

For now this re-defines the old macros. In future we may start using the
new macros directly, but that's a more intrusive search-and-replace.

Yury, I added a little bit more information to the commit message in
patch 1. First 2 patches may go through your tree. For the last one we
may have potential conflicts, so I'm not sure. +Jani from i915 side to
chime in.

v1: https://lore.kernel.org/intel-xe/20230509051403.2748545-1-lucas.demarchi@intel.com/
