[PATCH 3/3] parisc/mm: Drop all pxdp_get()

[Anshuman Khandual <anshuman.khandual@arm.com>]

Current platform specific pxdp_get() helpers are exact same as the default
ones defined in the generic MM header (include/linux/pgtable.h) thus making
them redundant. Move functions that are now depending on generic helpers to
avoid build failure.
