ARM: 9330/1: davinci: also select PINCTRL

kconfig warns when PINCTRL_SINGLE is selected but PINCTRL is not
set, so also set PINCTRL for ARCH_DAVINCI. This prevents a
kconfig/build warning:

   WARNING: unmet direct dependencies detected for PINCTRL_SINGLE
     Depends on [n]: PINCTRL [=n] && OF [=y] && HAS_IOMEM [=y]
     Selected by [y]:
     - ARCH_DAVINCI [=y] && ARCH_MULTI_V5 [=y]
