powerpc/64: Define new ISA v3.00 logical PVR value and PCR register value

ISA 3.00 adds the logical PVR value 0x0f000005, so add a definition for
this.

Define PCR_ARCH_207 to reflect ISA 2.07 compatibility mode in the processor
compatibility register (PCR).

[paulus@ozlabs.org - moved dummy PCR_ARCH_300 value into next patch]
