[U-Boot] [PATCH v2 8/9] spl: Introduce SPL_DM_GPIO Kconfig define

[Lukasz Majewski]

This define indicates if DM_GPIO shall be supported in SPL. This allows
proper operation of DM converted GPIO drivers in SPL, which use
#if !CONFIG_IS_ENABLED(DM_GPIO) to also support not yet DM/DTS converted
boards.
