qcacmn: Trim scan channel list

As requirement, concurrent mode, station 5G/2G scan need stop when AP
connected by peer station.

Condition:
STA + AP 5G (connected) + AP 2.4G	skip 5G scan
STA + AP 5G (connected)			skip 5G scan
STA + AP 2.4G (connected && 2.4G only)	skip 2.4G scan
Others concurrency			skip none

Add ini ch_list_trim_conc to enable/disable the feature. Default is
disabled.

Before send WMI_SCAN_CMD to firmware, call API
policy_mgr_scan_trim_chnls_for_connected_ap() to check if need
trim scan channel list. Which channel list need be trimmed
