[U-Boot] [PATCH 2/2] mmc: mtk-sd: fix SPL compilation when GPIO=y and SPL_GPIO=n

[Fabien Parent]

It is not possible to link the SPL image when CONFIG_GPIO is enabled
but CONFIG_SPL_GPIO is not.  Use the IS_ENABLED macro instead to
correctly check whether CONFIG_{SPL_}GPIO is enabled.

This commit fixes the following errors:
	* undefined reference to `dm_gpio_get_value
	* undefined reference to `gpio_request_by_name'
