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.
