ARM: dts: define clock binding for bcm21664 



Document the device tree binding for Broadcom BCM28164 clock control
units and clocks.  This SoC uses Kona CCUs, similar to the BCM281XX
SoC family.

BCM21664 family

---------------

CCU compatible string values for SoCs in the BCM21664 family are:

    "brcm,bcm21664-root-ccu"

    "brcm,bcm21664-aon-ccu"

    "brcm,bcm21664-master-ccu"

    "brcm,bcm21664-slave-ccu"



The following table defines the set of CCUs and clock specifiers for

BCM21664 family clocks.  When a clock consumer references a clocks,

its symbolic specifier (rather than its numeric index value) should

be used.  These specifiers are defined in:

    "include/dt-bindings/clock/bcm21664.h"
