Shouldn't this follow pinctrl config name like other sunXi SOCs?
This should be PINCTRL_SUN??_A64.
First, we should find family name for A64. I remember, on IRC Maxime
refering A64 to family named sun10i.

This bit is reffered as PCM in A64 user manual. you've named PCM1 as
i2s1 in PG pins.
It will be great if we follow same here, it should be i2s0; same for
PB5, PB6, PB7 pins.
In fact, PB3 above is i2s0 MCLK pin.
