[U-Boot] [PATCH] mx23: Put back RAM voltage level to its original value

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <fabio.estevam@freescale.com>

commit 5c2f444c9 (mxs: Reset the EMI block on mx23) changed the DDR voltage 
level, which causes mx23evk to fail to load a kernel.

Put back the original values, so that mx23evk can boot a kernel again.
