reg_is_range_overlap_6g() is not implemented for station solution,
if enable CONFIG_AFC_SUPPORT for mobile router, reg_set_ap_pwr_type()
will encounter compile issue.
reg_get_5g_bonded_channel_for_freq() updated to add more parameters
by Change Id I4c978c7f938b14d79d0eadf4251a86a9165f496e.
Fix it by adding CONFIG_REG_CLIENT check so reg_is_range_overlap_6g()
only valid for AP solution, because for mobile device there is no
deployment type (indoor/outdoor) set, so reg_set_ap_pwr_type() under
CONFIG_AFC_SUPPORT is for AP solution only, and only one pdev exist
for station solution so API reg_is_range_overlap_6g() is not needed,
query wmi_service_6ghz_support can get 6 GHz capability.
Update AFC/DCS function where call
wlan_reg_decide_6ghz_power_within_bw_for_freq().
