Simon Glass bb27b96f13 cpu: Enable reporting of faults ...

Faults should be enabled, otherwise we just get a hard fault whenever they
occur.

BUG=chrome-os-partner:10146
TEST=manual:
build and boot on snow; cause a fault and see that it is reported correctly
in the panic message, rather than just a hard fault.
Also tested on link, 'rw 1':

 > rw 1
