drm: remove pgprot_decrypted() before calls to io_remap_pfn_range()
commit f8f6ae5d077a ("mm: always have io_remap_pfn_range() set
pgprot_decrypted()") moves the pgprot_decrypted() into
io_remap_pfn_range(). Delete any, now confusing, open coded calls that
directly precede io_remap_pfn_range():
- drm_io_prot() is only in drm_mmap_locked() to call io_remap_pfn_range()
- fb_mmap() immediately calls vm_iomap_memory() which is a convenience
wrapper for io_remap_pfn_range()
