mtd: add CRC signature to RedBoot partition map

Browse Source 
The code for calculating the CRC32 signatures for RedBoot FIS partitions
was already included, but for unknown reasons, it was never invoked. Some
bootloaders enforce checking these for loaded kernels, so they should be
written. This patch does so.
