Oleksii Kurochko ba0d1a7ced xen/lib: introduce generic find next bit operations 
find-next-bit.c is common for Arm64, PPC and RISCV64,
so it is moved to xen/lib.

PPC has been transitioned to generic functions from find-next-bit.c
since it now shares the same implementation as the PPC-specific code.

The MISRA exclude list has been updated to verify
lib/find-next-bit.c instead of Arm's find_next_bit.c,
as Arm's find_next_bit.c has been relocated to xen/lib/.

Despite CONFIG_GENERIC_FIND_FIRST_BIT not currently being used in
Xen and being removed from the Linux kernel [1], it could theoretically
prove useful for Xen. This is because the Linux kernel transitioned
Arm to the generic version of find_first_bit() and
find_first_zero_bit() due to improvements [1] in both performance
and .text size.
It would be prudent to investigate whether [1] is applicable to Xen
as well and, if so, implement the necessary changes in a separate patch.
