0200db650e target-xtensa: add Avnet LX60/LX110/LX200 boards 
These boards carry similar hardware: SDRAM (48M for LX110, 64M for LX60,
96M for LX200), 16 Mbyte FLASH, FPGA, 10/100 Mbps Ethernet PHY and 16550
UART. FPGA may be loaded with almost any Tensilica processor. It is also
used to implement Ethernet MAC, e.g. OpenCores 10/100 Mbps Ethernet MAC
and LED/DIP switches access.
