erofs uses an additional address space for compressed data read from disk in addition to the one directly associated with the inode. Reading into the lower address space is open coded using add_to_page_cache_lru instead of using the filemap.c helper for page allocation micro-optimizations, which means it is not covered by the MM PSI annotations for ->read_folio and ->readahead, so add manual ones instead.
