Subject: mm: pgtable: introduce generic __tlb_remove_table()

Several architectures (arm, arm64, riscv and x86) define exactly the same
__tlb_remove_table(), just introduce generic __tlb_remove_table() to
eliminate these duplications.

The s390 __tlb_remove_table() is nearly the same, so also make s390
__tlb_remove_table() version generic.
