This patchset implements the MTD OTP functions to allow access to the SPI
OTP data. Specific support is added for the Adesto, Macronix and Winbond
flash chips.

In the past there was already an attempt by Rahul Bedarkar to add this, but
there was no response. These patches are slightly based on his work.
