pinctrl: renesas: Reintroduce SH_PFC for common sh-pfc code
Most, but not all, Renesas pin control drivers use the "sh-pfc" pin control framework. As of commit 8449bfa9e6a9f7ec ("pinctrl: sh-pfc: Collect Renesas related CONFIGs in one place"), the code for this framework is always built when Renesas SoC pin control support is enabled, regardless of whether the enabled pin control drivers need it or not. Fix this by reintroducing the CONFIG_SH_PFC symbol to control inclusion of the "sh-pfc" framework and its dependencies, and selecting it when needed. This reduces kernel size of a typical RZ/A1 or RZ/A2 kernel by more than 6 resp. 11 KiB.
