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

I wonder why arm64 doesn't define CONFIG_HAVE_REGS_AND_STACK_ACCESS_API?
That support is added in the patch I sent out after this one (to a
different set of recipients).
Thanks.
Thanks!
