The current definition of SWAPPER_TABLE_SHIFT can only be used in
asm code if the configured number of translation levels defines
PUD_SHIFT and/or PMD_SHIFT natively (4KB and 16KB/64KB granule,
respectively). Otherwise, it depends on the nopmd/nopud fixup
headers, which can only be included in C code.

So redefine SWAPPER_TABLE_SHIFT in a way that is independent of the
number of configured translation levels.
