The rk3228, rk3328, rk3399 have an interesting new feature,
some things like one specific uart can use multiple pins to
output data, but control of that seems to be split. The actual
pin config is identical for all pins - each needs to be configured
to function 2.

Use one pin of a specifc group to be set to its special pinmux function,
then configure the corresponding routing bits. If the pinmux setting is
wrong for that pin the ip block won't work correctly anyway.
