Subject: [PATCH] ramips: fix wifi mac address of HiWiFi series devices

For HiWiFi series devices, label_mac can be read from bdinfo partition,
and lan_mac, wlan2g_mac are same as the label_mac. Converting label_mac
to wlan5g_mac only needs to unset 6th bit. (It seems that all HiWiFi's
label_mac start with D4:EE)

For example:
label	D4:EE:07:32:84:88
lan	D4:EE:07:32:84:88
wan	D4:EE:07:32:84:89
wlan2g	D4:EE:07:32:84:88
wlan5g	D0:EE:07:32:84:88

Tested on HiWiFi HC5661.
