[PATCH 2/2] ARM: dts: ls1021a-qds: add compatible string "fsl,ls1021aqds-fpga" for on boards FPGA chip

[Frank . Li]

From: Frank Li <Frank.Li@xxxxxxx>

Add front compatible string "fsl,ls1021aqds-fpga" for on boards FPGA chip
and remove unused property bank-width and device-width, which used for
MTD devices and FPGA is not a MTD devices.

Fix below CHECK_DTBS warning:
rch/arm/boot/dts/nxp/ls/ls1021a-qds.dtb: memory-controller@1530000 (fsl,ifc): board-control@3,0: 'oneOf' conditional failed, one must be fixed:
        'bank-width', 'device-width' do not match any of the regexes: '^gpio@[0-9a-f]+$', '^mdio-mux@[a-f0-9,]+$', '^pinctrl-[0-9]+$'

                ['simple-mfd'] is too short
