KVM need this function when switching from vcpu to user-space
thread. My subsequent patch will use this function.

This patch adds the debug stub support on booke/bookehv.
Now QEMU debug stub can use hw breakpoint, watchpoint and
software breakpoint to debug guest.
This is how we save/restore debug register context when switching
between guest, userspace and kernel user-process:
When QEMU is running

This way we can use same data type struct with KVM and
also help in using other debug related function.

This patchset adds the userspace debug support for booke/bookehv.
this is tested on powerpc e500v2/e500mc devices.
We are now assuming that debug resource will not be used by kernel for its own
debugging. It will be used for only kernel user process debugging.
So the kernel
"ehpriv" instruction is used for setting software breakpoints
by user space. This patch adds support to exit to user space
with "run->debug" have relevant information.
As this is the first point we are using run->debug, also defined
the run->debug structure.

For KVM also use the "struct debug_reg" defined in asm/processor.h
