dt-bindings: clk: vc5: Make SD/OE pin configuration properties not required

Browse Source 
"make dtbs_check":

    arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: clock-generator@6a: 'idt,shutdown' is a required property
	    From schema: Documentation/devicetree/bindings/clock/idt,versaclock5.yaml
    arch/arm64/boot/dts/renesas/r8a77951-salvator-xs.dtb: clock-generator@6a: 'idt,output-enable-active' is a required property
	    From schema: Documentation/devicetree/bindings/clock/idt,versaclock5.yaml

Versaclock 5 clock generators can have their configuration stored in
One-Time Programmable (OTP) memory.  Hence there is no need to specify
DT properties for manual configuration if the OTP has been programmed
before.  Likewise, the Linux driver does not touch the SD/OE bits if the
corresponding properties are not specified, cfr. commit d83e561d43
("clk: vc5: Add properties for configuring SD/OE behavior").

Reflect this in the bindings by making the "idt,shutdown" and
"idt,output-enable-active" properties not required, just like the
various "idt,*" properties in the per-output child nodes.
