ice: use bitfields instead of unions for CGU regs

commit c6b4486

Switch from unions with bitfield structs to definitions with bitfield
masks. This is necessary, because some registers have different
field definitions or even use a different register for the same fields
based on HW type.

Remove unused register fields.
