arm64: dts: qcom: ipq8074: Remove unused gpio from QPIC pins

gpio16 will only be used for LCD support, as its NAND/LCDC data[8]
so its bit 9 of the parallel QPIC interface, and ONFI NAND is only 8
or 16-bit with only 8-bit one being supported in our case so that pin
is unused.

It should be dropped from the default NAND pinctrl configuration
as its unused and only needed for LCD.
