Subject[PATCH v4 1/7] arm64: sunxi: Kconfig: add essential pinctrl driver
The pinctrl driver is essential for the Allwinner SoCs to work.
Add the driver's config symbol to the Kconfig entry to always compile
it in. We can't use the arm approach to make the _driver's_ Kconfig
symbol def_bool, because we lack the MACH_* symbols in arm64.
That line was in the original pinctrl driver patch, but got removed
to avoid the dependency on the Kconfig patch [1].
Also add the general PINCTRL symbol, which isn't selected automatically
for the same reason.

This enables support for Allwinner sunxi based SoCs like the A64.
