After switching to the new FSL QSPI driver the properties
'fsl,qspi-has-second-chip' and 'big-endian' are not used anymore.
The driver now uses the 'reg' property to determine the bus and
the chipselect. The endianness is selected by the driver depending
on which SoC is used.

Hi Shawn/Leo,
Removing the "big-endian" property has caused problems in our UEFI firmware.
In UEFI, we use the device tree to detect and use the qspi controller and flashes attached to it.
We don't maintain a list of platforms like linux driver.
Can you please revert the endianness change from linux mainline ?
Regards,
Pankaj Bansal
