arm: dts: ls1088a: Update qspi node properties

Remove "num-cs" property from device-tree as it is no longer used by
qspi driver anymore.

Also, specify status as "disabled" and enable qspi support in respective
board dts files. This will also help in aligning node properties with
other board properties.
