esp_wifi: fix country policy issue
1. Fix not update phy according to country code.
2. Update regdomain max channel according to country info from nvs and or AP.
3. Change nvs default country from "CN" to "01".
4. Channel 14 is allowed only 11b mode.
5. Remove csa when switch channel from/to 14 channel.
6. Update phy mode nvs when softap channel from 14 to other.
7. Fix the bug that check whether channel parameter is valid.

The general conditions for using LR are:

- Both the AP and station are devices.

- Both the AP and station are Espressif devices.
|

- Long distance Wi-Fi connection and data transmission is required.

The default country info is {.cc="CN", .schan=1, .nchan=13, policy=WIFI_COUNTRY_POLICY_AUTO}. If the Wi-Fi mode is station/AP coexist mode, they share the same configured country info. Sometimes the country info of the AP to which the station is connected is different from the configured country info. For example, if the configured station has the country info of {.cc="JP", .schan=1, .nchan=14, policy=WIFI_COUNTRY_POLICY_AUTO}, but the connected AP has the country info of {.cc="CN", .schan=1, .nchan=13}, then the country info of the connected AP is used.
|

The default country info is::
|

};
|

If the Wi-Fi Mode is station/AP coexist mode, they share the same configured country info. Sometimes, the country info of AP, to which the station is connected, is different from the country info of configured. For example, the configured station has country info::

.cc = "JP",
|
||||
.schan = 1,
