[PATCH 2/7] pinctrl: rockchip: make use of pinconf-generic.h

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

So far we defined our own enum to record what bias was indicated by the
device tree properties. Now that we have imported the upstream enum
definition, make use of it to make syncs with Linux easier.

While at it, we replace one usage of RK_BIAS_PULL_UP with `1'. That they
were equal before was a coincidence and now that we use the Linux
definitions, this is no longer the case.
