This patch updates the source against the 2013.10-rc2 release; this
also renames the u-boot-mxsboot recipe to u-boot-fslc-mxsboot so it
makes it clear that it is based on u-boot-fslc version.

The license checksum has changes as U-Boot now uses SPDX Unique
License Identifiers (eca3aeb Licenses: introduce SPDX Unique Lincense
Identifiers).
