[U-Boot] [PATCH 1/1] efi_loader: efi_net: hwaddr_size = 6

The length of a MAC address is 6.
We have to set this length in the EFI_SIMPLE_NETWORK_MODE
structure of the EFI_SIMPLE_NETWORK_PROTOCOL.
Without this patch iPXE fails to initialize the network with
error message
SNP MAC(001e0633bcbf,0x0) has invalid hardware address length 0
