Move duplicate and functionally equivalent code for accessing registers
and stack (CONFIG_HAVE_REGS_AND_STACK_ACCESS_API) from arch subdirs into
common kernel files.

Note: Help regression testing s390, hexagon, and sh would be appreciated.
      Powerpc builds but I have not verified the functionality.

  Move the pt_regs_offset struct definition from arch to common include

Nice cleanup! The ARMy bits all look fine to me.
