Subject: pinctrl: sunxi: add a missing function of A10/A20 pinctrl driver

From: Icenowy Zheng <[email protected]>

commit d81ece747d8727bb8b1cfc9a20dbe62f09a4e35a upstream.

The PH16 pin has a function with mux id 0x5, which is the DET pin of the "sim" (smart card reader) IP block.

This function is missing in old versions of A10/A20 SoCs' datasheets and user manuals, so it's also missing in the old drivers. The newest A10 Datasheet V1.70 and A20 Datasheet V1.41 contain this pin function, and it's discovered during implementing R40 pinctrl driver.

Add it to the driver. As we now merged A20 pinctrl driver to the A10 one, we need to only fix the A10 driver now.

Fixes f2821b1ca3a2 ("pinctrl: sunxi: Move Allwinner A10 pinctrl

driver to a driver of its own")
