u-boot-aspeed: u-boot on eMMC support

This adds a new configuration ast2600_openbmc_spl_emmc_defconfig that
can be used on either emmc or nor systems. Note that it will try to
locate the environment on emmc, so use on nor-only systems will always
use the default environment.

Machines that wish to use this configuration should set UBOOT_MACHINE in
their <machinename>.conf.
