I agree. This is what ePAPR says should be present for caches along with 
a more specific string.

Based on the prior discussion on pmu naming, it should be the specific 
model. There is no such thing as a pl2x0. The models of L2 controllers 
the cache-l2x0.c code supports are:

PL310
L220
L210

And my compatible strings reflect that.

Will do.
