xtensa: mm: fix PMD folding implementation
There was a definition of pmd_offset() in arch/xtensa/include/asm/pgtable.h that shadowed the generic implementation defined in include/asm-generic/pgtable-nopmd.h. As the result, xtensa had shortcuts in page table traversal in several places instead of doing level unfolding. Remove local override for pmd_offset() and add page table unfolding where necessary.
