This adds hmp 'info tlb' command support for the arm platform.
The limitation is that this only implements a page walker for
ARMv8-A AArch64 Long Descriptor format, 32bit addressing is
not supported yet.

To reuse existing code, this patch also extracts some APIs from
helper.c, including regime_translation_disabled(),
pt_start_level_stage1(), regime_ttbr(), arm_ldq_ptw().

v4:
    Dividing the patch into two parts.
    Removed some of the previously described
    problems by switching to arm_ldq_ptw().
v3: rebase to latest mainline.
v2:
    o fix coding style
    o extract common code pt_start_level_stage1()
