[PATCH v2 4/4] Add Macronix SPI-NOR mx25l12833f with OTP.

[Erez Geva]

From: Erez Geva <ErezGeva2 at gmail.com>

mx25l12833f uses the same JEDEC ID as mx25l12805d.

The 2 chips have the same flash size.
So user can use mx25l12805d setting with mx25l12833f chip.

mx25l12833f support SFDP and have a bigger symmetric OTP.

Macronix annonce the end of life of mx25l12805d in 2010.

See:
  "https://www.macronix.com/Lists/TechDoc/Attachments/9861/PCN31_2009 PCN_MX25L6405D and MX25L12805D.pdf"
