Add support for Rockchip rk3588 variant of pinctrl.
The driver is adapted from the Linux driver.

It would be good if it tested with any function, does it?

Hello Jagan,
To test it with GPIO, I also added this patch to my test bench :
https://patchwork.ozlabs.org/project/uboot/patch/20230213222742.135093-8-mac...
And then, I was able to test with GPIO : powering up a LED , powering it down, also tested USB host by having the VBUS powered up by GPIO / powered down.
Other pinctrl functions tested were to boot from SD-Card, in which U-boot sets the right pinfunc for the SD pins.
