[U-Boot] [PATCH 3/3] imx: mx6slevk: enable more DM drivers

Sat Mar 4 02:45:44 UTC 2017
Enable more DM drivers. The imx I2C/MMC DM drivers needs DM_GPIO
enabled. So needs to enable them together.
DM FEC and SPI are not enabled, but they use gpio in board code.
So use gpio_request first to request the gpio, because DM_GPIO
is enabled.
