PATCH v2 1/1 ARM: mach-omap2: omap3: Fix GPIO clocking in SPL

OMAP3_GPIO_x is needed to enable each GPIO bank on the OMAP3 boards. At one point, the #ifdef's were replaced with if CONFIG_IS_ENABLED but this won't work for people who need OMAP3_GPIO_x in SPL since the SPL prefix for this option isn't used in Kconfig. This patch moves the check to #if defined and also makes Kconfig select the banks if CMD_GPIO is used which makes the checks in the code less cumbersome.

Fixes bd8a9c14c91c ("arm: mach-omap2/omap3/clock.c: Enable

all GPIO with CMD_GPIO")
