pinctrl: rockchip: Add RV1106 pinctrl support

Browse source

Add pinctrl support for the Rockchip RV1106, based on the vendor
kernel in the Luckfox Pico SDK [1] at commit 824b817f8 (a Linux
5.10.160 kernel tree). Each GPIO bank has its own IO control (IOC)
register block, referenced by the rockchip,grf phandle of the bank
node; the register offsets are relative to the bank's own block. The
drive strength uses the RK3568-style exponential encoding and only
pins 0-6 of GPIO0 have drive-strength registers.

The RV1103 is a package variant of the RV1106 with fewer pins and uses
the same pin controller.
