Fix bug of get_addr() in fdt_decode.c.

The original description is to match the field holding "one address with
no trailing data". So the if condition should be equal length:
  if (cell && len != sizeof(addr_t))

But it still worked fine except the lcd frame-buffer value because all
other fields are somethings like: reg = <0x70006040 0x40>, not exactly one
address.

So this CL fixed the matching to either one address or two addresses.

BUG=chrome-os-partner:5338
TEST=build without error and manually print the frame-buffer value to verify.
