layerscape: Fix SPI-NOR issues with vendor patches
For some reason LS1012A and LS1046A devboards don't work well with
Spansion SPI NOR flash. It cause read and write errors like:

NXP have found workarround and applied in their vendor kernel version.
They force 1x tx and 1x rx lines in qspi. That method fix issues.
This patch ports patches from NXP LSDK tree.
