Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are
all special world-wide compatibility ccode-s. Most of these world-wide
ccode-s allow passive scan mode only for 2.4GHz channels 12-14,
only enabling them when an AP is seen on them.
Since linux-firmware has moved to the new cyfmac4356-pci.bin +
cyfmac4356-pci.clm_blob firmware files this no longer works and
4356 devices using e.g. an X2 ccode fail to connect to an AP on
channel 13.
Add the 4356 chip-id to the list of chips for which to use the ISO3166
country code + rev 0 as fallback in brcmf_translate_country_code() to
fix this.
