    mediatek: dts: remove useless SPI cs-gpios property
    
    These devices only have one SPI peripheral. And the chip select pin is
    directly controlled by the SPI host hardware. Hence we don't need to
    assign empty GPIO phandle for them. This patch also adjust the reg
    address of the SPI peripheral node to follow the cs-gpios changes.
