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")

V2:  change if defined(OMAP3_GPIO_x) to include the CONFIG_ prefix

Applied to u-boot/master, thanks!
