[U-Boot] [PATCH V6 - Part 2 - 0/3] mxc_spi refactoring (for mx6q and mx6qsabrelite)

[Eric Nelson]

This patch set refactors mxc_spi as described in 
    http://lists.denx.de/pipermail/u-boot/2010-March/068791.html   
and requested in 
    http://lists.denx.de/pipermail/u-boot/2012-January/116023.html
in order to add support for the MX6Q in general and the mx6qsabrelite 
specifically.

Patch 1 simply moves the conditional parts of mxc_spi.c into the
respective CPU-specific imx-regs.h files.

Patch 2 adds general support for SPI to the i.MX6.

Patch 3 adds support to the mx6qsabrelite board
