ARM: UniPhier: support 1CS support card for all the UniPhier SoCs
Two support card variants are used with UniPhier reference boards: - 1 chip select support card (original CPLD) - 3 chip selects support card (ARIMA-compatible CPLD) Currently, the former is only supported on PH1-Pro4, but it can be expanded to PH1-LD4, PH1-sLD8 with a little code change.
