qcacmn: Add support for chan RF info from service_ready_ext event

Browse source 
Channel RF info contains metrics that signify the throughput
availability of all the supported channels. This information
is sent in as discrete TLVs (per channel) as part of the WMI
extended service ready event.

Each TLV contains the frequency, bandwidth represented and
the actual channel metric.

Add support to read the above-mentioned TLVs from the extended
service ready event
