qcacmn: Get per channel pno scan config service capability

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

If firmware supports WMI_SERVICE_PNO_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.
