Convert regs_{avail,dirty} and all related masks to "unsigned long" values
as an intermediate step towards declaring the fields as actual bitmaps, and
as a step toward support APX, which will push the total number of registers
beyond 32 on 64-bit kernels.
Opportunistically convert TDX's ULL bitmask to a UL to match everything
else (TDX is 64-bit only, so it's a nop in the end).
No functional change intended.
