CYW43438 ・ wiced_wps_enrollee function can't get credentials for WiFi channels 12 and 13

[KEKA_4568351]

In the following environment, with the wiced_wps_enrollee function, a phenomenon has occurred in which credentials for channels 12 and 13 of WiFi cannot be obtained.

Channels 1 to 11 are connected to a credential acquisition and WiFi connection.

Channels 12 and 13 cannot have credentials and cannot call subsequent WIFI connections (wifi_utils_join function).

The wps_host_scan function is implemented to scan the channel list for "1-14".
