Following some feedback from Greg, I've updated this series to be more
of a generic OTP layer. Everything is now registered under the "otp"
bus and I've also converted the blackfin OTP driver to use this
framework (which is the only current OTP driver I could find).

Mike, I wasn't 100% sure how big the blackfin OTP is but I found a
datasheet talking about 64KB so I've assumed that for now.

Main changes since v1:

- both devices and regions are now on the "otp" bus.
- moved to drivers/otp.
- converted bfin-otp to the generic OTP layer.

Jamie Iles (4):
drivers/otp: add initial support for OTP memory
drivers/otp: add support for Picoxcell PC3X3 OTP
drivers/otp: allow an ioctl to be specified
drivers/otp: convert bfin otp to generic OTP
