arm64: mm: Simplify __TLBI_RANGE_NUM() macro

Browse Source 
Since commit e2768b798a ("arm64/mm: Modify range-based tlbi to
decrement scale"), we don't need to clamp the 'pages' argument to fit
the range for the specified 'scale' as we know that the upper bits will
have been processed in a prior iteration.

Drop the clamping and simplify the __TLBI_RANGE_NUM() macro.
