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.

Changes in v4:
- Convert spaces to tabs.
Changes in v3:
- Rebase against latest u-boot-imx/master.
- Fix the number of banks on i.MX6.
- Rename iim to ocotp on i.MX6 in order to avoid confusion, and merge in the
existing gp1 fuse definition.
- Rename fuse_data to read_fuse_data, and sticky to sw_sticky, according to the
reference manual.
Changes in v2:
- Rebase against latest master.
