Add time sync configuration api.
The new api allows to configure the synchronization
mode (STA/AP/MESH) and (in case of Mesh mode) the
master address of each zone.

The struct cfg80211_pmksa defines its bssid field as:

    const u8 *bssid;

contrary to struct brcmf_pmksa, which uses:

    u8 bssid[ETH_ALEN];

Therefore in brcmf_cfg80211_del_pmksa(), &pmksa->bssid takes the address
of this field (of type u8**), not the one of its content (which would be
u8*).  Remove the & operator to make brcmf_dbg("%pM") and memcmp()
behave as expected.

This bug have been found using a custom static checker (which checks the
usage of %p... attributes at build time).  It has been introduced in
commit 6c404f34 ("brcmfmac: Cleanup pmksa cache handling code"),
which replaced pmksa->bssid by &pmksa->bssid while refactoring the code,
without modifying struct cfg80211_pmksa definition.

Replace &pmk[i].bssid with pmk[i].bssid too to make the code clearer,
this change does not affect the semantic.

Some RTL8821AE devices sold in Great Britain have the country code of
0x25 encoded in their EEPROM. This value is not tested in the routine
that establishes the regulatory info for the chip. The fix is to set
this code to have the same capabilities as the EU countries. In addition,
the channels allowed for COUNTRY_CODE_ETSI were more properly suited
for China and Israel, not the EU. This problem has also been fixed.
