Frank Li 06ce29264f dt-bindings: rtc: pcf85063: remove quartz-load-femtofarads restriction for nxp,pcf85063
Original TXT binding doc have not limitition about quartz-load-femtofarads,
which only allow 7000 for nxp,pcf85063.

So remove it to fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/imx/imx6dl-skov-revc-lt2.dtb: rtc@51 (nxp,pcf85063): quartz-load-femtofarads:0: 7000 was expected
        from schema $id: http://devicetree.org/schemas/rtc/nxp,pcf85063.yaml#
