arm64: mm: Introduce a C wrapper for by-range TLB invalidation

Browse source

As part of efforts to reduce our reliance on complex preprocessor macros
for TLB invalidation routines, introduce a new C wrapper for by-range
TLB invalidation which can be used instead of the __tlbi() macro and can
additionally be called from C code.

Each specific tlbi range op is implemented as a C function and the
appropriate function pointer is passed to __tlbi_range(). Since
everything is declared inline and is statically resolvable, the compiler
will convert the indirect function call to a direct inline execution.
