The usage of the preboot feature is now controlled via a separate Kconfig
option - namely CONFIG_USE_PREBOOT.
It must be enabled for preboot code executing commands now defined in
CONFIG_PREBOOT (also moved to the Kconfig).

After defining both CONFIG_USE_PREBOOT and CONFIG_PREBOOT in
imx28_xea_defconfig the define of CONFIG_PREBOOT shall be removed from
xea.h as it is redundant.

Since linux commit 2e6cde96873253fd9eb0f20afd8ffd18278cff75 ("arm64:
dts: ls1028a: make the eMMC and SD card controllers use fixed indices")
mmc0 is the eMMC and mmc1 is the SD card. Also swap it in u-boot to
avoid any confusion by the user and to be aligned with linux.
