[v2,0/4] pinctrl: rockchip: fix RK3328 pinmux bits

Message

The pinmux settings for RK3328 is incomplete, correct the pin bank
settings and recalced mux data according to RK3328 TRM[1].

There was a patch[2] in rockchip-linux kernel repo that cover part of
missing mux settings, unfortunatly it never got into upstream kernel
source.

The last patch fixes an issue in rockchip_pmx_set which is general for
all rockchip platforms that might cause unexpected pinmux to be set to
0.
