Manjunathappa, Prakash - Feb. 23, 2012, 1:58 p.m.
NAND and NOR device are made as aemif device slaves, hence all DaVinci
board NAND/NOR device registration is achieved via emif MFD driver.

Signed-off-by: Manjunathappa, Prakash <prakash.pm@ti.com>
---
Since v4:
No change.
Since v3:
Changed NAND device id to 1 for board-mityomapl138.
Since v2:
Make changes for all DaVinci boards in single patch.
Since v1:
Patch generated using -M option.
