8f3ff11c1f imx: Homogenize and fix fuse register definitions
IIM:
 - Homogenize prg_p naming (the reference manuals are not always self-consistent
   for that).
 - Add missing SCSx and bank registers.
 - Fix the number of banks on i.MX53.

OCOTP:
 - Rename iim to ocotp in order to avoid confusion.
 - Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the
   reference manual.
 - Merge the existing spinoff gp1 fuse definition on i.MX6.
 - Fix the number of banks on i.MX6.

8de16794a0 mxs: mxsboot: Move sdcard BCB header to 4 sectors offset
The MX23 Boot ROM does blindly load from 2048 offset while the MX28
does parse the BCB header to known where to load the image from. We
move the BCB header to 4 sectors offset so same code can be used by
both SoCs avoiding code duplication.

492938a334 nitrogen6x: Setup CCM_CCOSR register

Doing this setup in the bootloader will allow us to remove a lot of code in

Also, according to Eric Nelson: "enabling the clock <in the bootloader> will
remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."

The ARM errata 742230 - "ARM errata: DMB operation may be faulty" is
claimed for Cortex-A9 (r1p0..r2p2).  Though i.MX6 uses a newer revision
than r2p2, we are seeing a reboot failure on i.MX6 SMP build that can be
fixed by applying the workaround for this errata.  So for safety, let's
define CONFIG_ARM_ERRATA_742230 to enable the workaround on i.MX6.
