The commit 0c8ea531b774 ("arm64: mm: Allocate ASIDs in pairs") introduce
the asid2idx and idx2asid macro, but these macros are not really useful
after the commit f88f42f853a8 ("arm64: context: Free up kernel ASIDs if
KPTI is not in use").
The code "(asid & ~ASID_MASK)" can be instead by a macro, which is the
same code with asid2idx(). So rename it to ctxid2asid() for a better
understanding.
Also we add asid2ctxid() macro, the contextid can be generated based on
the asid and generation through this macro.
