This adds support for userspace to control the HW debug registers for

As we haven't always had guest debug support we need to probe for it.
Additionally we don't do this in the start-up capability code so we
don't fall over on old kernels.

This adds support for single-stepping the guest. To do this we need to
manipulate the guests PSTATE.SS and MDSCR_EL1.SS bits which we do in the
kvm_arm_setup/clear_debug() so we don't affect the apparent state of the
guest.

If we can't find details for the debug exception in our debug state
then we can assume the exception is due to debugging inside the guest.
To inject the exception into the guest state we

You may be wondering what happened to v3 and v4. They do exist but
they didn't change much from the the original patches as I've been
mostly looking the kernel side of the equation. So in summary the
changes are:

The elr_el2 and spsr_el2 registers in fact contain the processor state
before entry into EL2. In the case of guest state it could be in either
el0 or el1.
