[PATCH V2] Skip unnecessary pte makeup when clearing it

If we are only about to clear a hardware pte entry, then pte makeup code is
unnecessary for cpu_v7_set_pte_ext and armv6_set_pte_ext, so just skip it.

Changes for V2:
    - Use "1f" instead of "set_pte" as label
    - Build/bootup test with thumb mode
    - checkpatch script shows:
total: 0 errors, 0 warnings, 44 lines checked

./0001-Skip-unnecessary-pte-makeup-when-clearing-it.patch has no obvious style problems and is ready for submission.
