[U-Boot] [PATCH 3/3] arm: socfpga: mcvevk: Minor tweaks to the default env

Polish the environment a bit, add two new variables so that the MMC
boot and root partitions are not explicitly hard-coded in the env.
Use one less if condition in the try_bootscript and handle possible
mmc rescan failure there.
