arm64: mm: Use __pa_symbol() for set_swapper_pgd()
commit 2330b7ca78350efcb ("arm64/mm: use fixmap to modify
swapper_pg_dir") modifies the swapper_pg_dir via the fixmap
as the kernel page tables have been moved to a read-only
part of the kernel mapping.
Using __pa() to setup the fixmap causes CONFIG_DEBUG_VIRTUAL
to fire, as this function is used on the kernel-image swapper
address. The in_swapper_pgdir() test before each call of this
function means set_swapper_pgd() will only ever be called when
pgdp points somewhere in the kernel-image mapping of
swapper_pd_dir. Use __pa_symbol().
