Subject: [PATCH 0/3] Migrate i8255 GPIO drivers to regmap API

The regmap API supports IO port accessors so we can take advantage of
regmap abstractions rather than handling access to the device registers
directly in the driver.

Precursor patches are provided for 104-dio-48e and 104-idi-48 to migrate
their respective device-specific registers first in order to simplify
the subsequent patch migrating the i8255 library and its dependents.

The struct i8255 control_state member serves as a cache of the i8255
device's control register. Does the regmap API support caching such that
we won't need to manually update a control_state member?
