Update SRCREV and SRCBRANCH, change the names of the m4 demos that are
installed into imx-boot, change the name of the SECO firmware (ahab container)
and update our patch so it applies over the newest revision of imx-mkimage.
For the time being, use the B0 SECO firmware for all i.MX8QXP platforms and add
the changes needed for C0 support in comments.
