[PATCH] powerpc: add defintion for MSR[GS] to list of MSR bits

[Michael Neuling]

> Add macros for the GS (guest state) bit to the list of MSR bit definitions.
> On PowerPC cores that support embedded hypervisor mode, GS is cleared if
> the system is running in hypervisor state (and MSR[PR] is cleared), and set
> if it's running in guest state.  See the Power ISA 2.06 specification for
> more information.

Shouldn't this be in reg_booke.h?
