--------------------------------

commit fc153c8f upstream.

H6 requires I/O bias configuration on both of its PIO devices.
Previously it was only done for the main PIO.

The setting for Port L is at bit 0, so the bank calculation needs to
account for the pin base. Otherwise the wrong bit is used.

Fixes: cc62383f ("pinctrl: sunxi: Support I/O bias voltage setting on H6")
