pinctrl: uniphier: omit redundant input enable bit information
For LD11/20 SoCs (capable of per-pin input enable), the iectrl bit
number matches its pin number. So, this is redundant information.
Instead, we just need a flag to know if the iectrl gating exists or not.
With this refactoring, 5 bits in pin data will be saved.
