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

+description: |
+  Broadcom "Kona" style clock control unit (CCU) is a clock provider that
+  manages a set of clock signals.

+  All available clock IDs are defined in
+  - include/dt-bindings/clock/bcm281xx.h for BCM281XX family
+  - include/dt-bindings/clock/bcm21664.h for BCM21664 family
