Ethernet hardware address stored in DC_AL_PAR0/DC_AL_PAR1 register

Browse source 
is in little endian form. Likewise setting DC_AL_PAR0/DC_AL_PAR1
register expect the address to be in little endian form. For big
endian architectures the address should be swapped to get correct
one.
Change setting/getting ethernet hardware address to big endian
architecture frendly.
