Boards Broadcom cable/DSL/settop SoC shall have the following properties.

mips-hpt-frequency:
description: MIPS counter high precision timer frequency.
This is common to all CPUs in the system so it lives
under the "cpus" node.
$ref: /schemas/types.yaml#/definitions/uint32
brcm,bmips-cbr-reg:
description: Reference address of the CBR.
Some SoC suffer from a BUG where CBR(Core Base Register)
address might be badly or never initialized by the Bootloader
or reading it from co-processor registers, if the system boots
from secondary CPU, results in invalid address.
The CBR address is always the same on the SoC hence it
can be provided in DT to handle these broken case.
