dt-bindings: mtd: gpmi-nand: Fix matching of clocks on different SoCs 



Driver requires different amount of clocks for different SoCs.  Describe
these requirements properly to fix dtbs_check warnings like:

    arch/arm64/boot/dts/freescale/imx8mm-beacon-kit.dt.yaml: nand-controller@33002000: clock-names:1: 'gpmi_apb' was expected
