arm64: tlb: Improve __TLBI_VADDR_RANGE()

The macro returns the operand of TLBI RANGE instruction. A mask needs
to be applied to each individual field upon producing the operand, to
avoid the adjacent fields can interfere with each other when invalid
arguments have been provided. The code looks more tidy at least with
a mask and FIELD_PREP().
