qcacmn: Get per channel scan config service capability

Firmware advertises the service capability bit
WMI_SERVICE_SCAN_CONFIG_PER_CHANNEL when it supports per channel
scan config flags. Get this and cache in psoc.

If firmware supports WMI_SERVICE_SCAN_CONFIG_PER_CHANNEL, it uses
the upper-12 bits(bit-20 to bit 32) of channel_list for flags and
lower 20-bits(bit-0 to bit-19) for frequency. If firmware doesn't
support it, then channel_list holds the frequency value only.
Fill the flags and frequency accordingly.
