mvebu: fix partition type and signature for sdcard

Previously the partition signature was assigned from provided type. Now
both are corrected wherein signature is always generated from
SOURCE_DATE_EPOCH. With that the root file system can be identified
by PARTUUID string, without relying on static declaration of device node.
This commit also does some cosmetics, removing trailing whitespace and
replacing spaces with tab.
