OMAP: GPIO: fix _set_gpio_triggering() for OMAP2+

In case on OMAP2+ we call set_24xx_gpio_triggering() instead of
updating reg and l values. However, at the end of the function we
perform a write:

	__raw_writel(l, reg);

So on OMAP2+ we end up writing 0 to the bank->base which is not
correct (typically this points to GPIO_REVISION register).

Fix this by returning immediately after call to
set_24xx_gpio_triggering().
