Enable SPI flash support under U-Boot and SPL. The ENV size and offset,
ported from U-Boot 2013.01 Marvell version: 2015_T1.0p16
To create U-Boot image for SPI flash, user would need to replace
* CONFIG_MVEBU_SPL_BOOT_DEVICE_MMC with CONFIG_MVEBU_SPL_BOOT_DEVICE_SPI
* CONFIG_ENV_IS_IN_MMC with CONFIG_ENV_IS_IN_SPI_FLASH

v2:
* Move u-boot specific properties into armada-388-helios4-u-boot.dtsi
