e8e36d2f18 pinctrl: sh-pfc: r8a73a4: Remove obsolete multi-platform check 
As of commit 9d07d414d4 ("ARM: shmobile: r8a73a4: ape6evm: Remove
legacy platform"), r8a73a4 is only supported in generic ARM
multi-platform builds.  Hence CONFIG_ARCH_MULTIPLATFORM is always set,
and the check can be removed.

51128e8ac8 pinctrl: sh-pfc: rename confusing pinmux ops variable 
The vtable named *pinmux_ops in the affected files are not really
about pin multiplexing, but a struct related to some PFC-specific
operations, inclusing pin config (bias setting). Rename the variable
so as to avoid confusions.

Add initial PFC support for the r8a73a4 SoC.

Original authors are Morimoto-san with help from Yoshii-san, thanks to
them for the heavy lifting. Adjusted by Magnus to work together with
updated code in drivers/pinctrl.
