Leave pca953x P06,P07 pins on b850v3 platform and P06 pin on
b450v3/b650v3 unconfigured in the kernel space since they could be
configured as DP1_RST and DP2_RST by the applications for the DP FW
update support.

Since commit b36581df7e ("spi: imx: Using existing properties for
chipselects") the device tree property 'fsl,spi-num-chipselects' is
unused and it is already marked as obsolete in device tree binding
documentation. Remove the property from the existing DTS files to
avoid its reoccurence on copying.

unexpected interrupts. Configure the unused pins as GPO low to
avoid unexpected interrupts.

Advantech has 3 carrier boards (B450v3, B650v3, B850v3) which use
the Advantech BA-16 module (based on iMX6D). This file has the
devicetree entries that are common to all 3 boards.
