perf tools arch powerpc: Add register mask for power11 PVR in extended regs

Perf tools side uses extended mask to display the platform supported
register names (with -I? option) to the user and also send this mask to
the kernel to capture the extended registers as part of each sample.
This mask value is decided based on the processor version ( from PVR ).

Add PVR value for power11 to enable capturing the extended regs as part
of sample in power11.
