dt-bindings: clock: brcm,kona-ccu: convert to YAML
Convert Broadcom Kona family clock controller unit (CCU) bindings
to DT schema.
Changes during conversion:
- remove "dmac" from clock-output-names for brcm,bcm11351-master-ccu,
such a clock doesn't exist
- remove "uartb4" from clock-output-names for brcm,bcm21664-slave-ccu,
such a clock doesn't exist
