[U-Boot] [PATCH 2/4] configs: at91sam9n12ek: update for DT and DM support

Tue Feb 28 01:28:24 UTC 2017

Support the device tree and enable CONFIG_CLK and CONFIG_PINCTRL
options to support at91 clock driver and at91 pinctrl driver.

Enable DM_GPIO, DM_MMC and DM_SPI support, move CONFIG_AT91_GPIO,
CONFIG_GENERIC_ATMEL_MCI and CONFIG_ATMEL_SPI config option to
the default config files.

Due to the limitation of internal SRAM size, disable the CONFIG_SPL
config option for the spi flash configuration.
