For the record, it wasn't enough to enable the regmap caching, we also
need to fill up the cache on init by specifying the num_reg_defaults_raw
parameter.

This uncovered another problem where the pin control "enable" bit was
unsettling because the default regmap values were initialized to zeros
and driver doesn't set the enable bit at all.
