mx23: Put back RAM voltage level to its original value
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. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Tested-by: Robert Nelson <robertcnelson@gmail.com>
