pinctrl: uniphier: split pinctrl driver for PH1-LD11 and PH1-LD20
PH1-LD11 and PH1-LD20 have much pin controlling in common, so I added a single driver shared between them in the initial commit. However, the Ethernet pin-mux settings I am going to add are different with each other, and they may diverge more as the progress of development. Split it into two dedicated drivers.
