l2x0_init() allows to overwrite bits in the AUX_CTRL register
using the aux_val/aux_mask arguments. On i.MX35 this is used
to pass a correct AUX_CTRL value to overwrite bogus reset values
for this register. To make this work we have to apply
aux_val/aux_mask before using the AUX_CTRL value to determine the
way size.
This fixes: 3f7e890da7 ARM: l2x0: Implement L310 support
Before this commit the way size was hardcoded to 8.
