nx823: get mac address from environment
The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
For the nx823, the serial number is moved out of load_sernum_ethaddr() and
into misc_init_r() as is the env setup. This lets us kill off the former
function in the process.
