ramips: TEW-692GR: fix switch and wireless

Browse Source 
The AR8327 initvals were not copied to the DTS during the switch from
mach file to device tree and broke the switch on the device.

The former used PORT6 related initvals were wrong and have been
corrected.

The phy mode setting for the switch was missing in the DTS as well.

The wireless requires an eeprom to work. The dual band wireless chips
have both bands enabled by default but only one band per chip is
working.

The stock firmware uses the following mac addresses:

LAN:    AA:BB:CC:DD:EE:E4
WAN:    AA:BB:CC:DD:EE:E4
2.4GHz: AA:BB:CC:DD:EE:E4
5 GHz:  AA:BB:CC:DD:EE:E8

Assuming the mac address range :E4 to :E8 is reserved for this device,
the MAC addresses were reorder to have a unique MAC address for each
interface:

LAN:    AA:BB:CC:DD:EE:E4
2.4GHz: AA:BB:CC:DD:EE:E4
WAN:    AA:BB:CC:DD:EE:E5
5 GHz:  AA:BB:CC:DD:EE:E8
