pinctrl: sprd: Fix the kconfig warning

On X86 plaform, if the CONFIG_OF is not selected, and set the
CONFIG_SPRD_SC9860 as 'm', that will cause below waring:

WARNING: unmet direct dependencies detected for PINCTRL_SPRD
  Depends on [n]: PINCTRL [=y] && OF [=n] && (ARCH_SPRD || COMPILE_TEST [=y])
  Selected by [m]:
  - PINCTRL_SPRD_SC9860 [=m] && PINCTRL [=y]

Thus move the configuration dependency under CONFIG_PINCTRL_SPRD_SC9860
to fix the warning.
