Subject: [PATCH 05/20] wifi: rtl8xxxu: support setting mac address register for both interfaces

To prepare for concurrent mode, enhance rtl8xxxu_set_mac() to write the
mac address of the respective interface to REG_MACID or REG_MACID1.

Remove the call to rtl8xxxu_set_mac() from the init function as we set
it in rtl8xxxu_add_interface() later anyway.

Until rtl8xxxu_add_interface() can handle both interfaces, call
rtl8xxxu_set_mac() with port_num = 0.
