All CP15 processors need not have processor feature registers, only
for architectures defined by CPUID scheme would have it. Hence check
for it before accessing processor feature register, ID_PFR1.

Hi Russell,
It would be good to have the fix go in during -rc, as,
1. Culprit commit went in during the last merge window
2. Though nothing supported in mainline is known to be broken, the
original change needs to be modified to be reliable
