Subject: [PATCH] pinctrl: at91: fix CONFIG_OF dependency

From: Arnd Bergmann <arnd@...db.de>

Selecting OF_GPIO is not allowed when CONFIG_OF is disabled:

WARNING: unmet direct dependencies detected for OF_GPIO
  Depends on [n]: GPIOLIB [=y] && OF [=n] && HAS_IOMEM [=y]
  Selected by [y]:
  - PINCTRL_AT91 [=y] && PINCTRL [=y] && (OF [=n] && ARCH_AT91 || COMPILE_TEST [=y])

WARNING: unmet direct dependencies detected for MFD_STMFX
  Depends on [n]: HAS_IOMEM [=y] && I2C [=y] && OF [=n]
  Selected by [y]:
  - PINCTRL_STMFX [=y] && PINCTRL [=y] && I2C [=y] && OF_GPIO [=y]

WARNING: unmet direct dependencies detected for GPIO_SYSCON
  Depends on [n]: GPIOLIB [=y] && HAS_IOMEM [=y] && MFD_SYSCON [=y] && OF [=n]
  Selected by [y]:
  - GPIO_SAMA5D2_PIOBU [=y] && GPIOLIB [=y] && HAS_IOMEM [=y] && MFD_SYSCON [=y] && OF_GPIO [=y] && (ARCH_AT91 || COMPILE_TEST [=y])

Add back the unconditional CONFIG_OF dependency, but leave COMPILE_TEST
as an option when that is enabled.

Fixes: 8e86af65f39d ("pinctrl: at91: allow building the module with COMPILE_TEST=y")
