net: tsec: add support for promiscuous mode

Browse source 
The Freescale TSEC can be a DSA master, and the ports of the attached
DSA switch can have different MAC addresses compared to the TSEC.
Nonetheless, the TSEC must receive the packets on behalf of those switch
ports. Therefore, implement the promiscuous mode method to allow DSA to
set this.

Note that the init_registers() function called from eth_ops :: start
overwrites this setting. There is no reason why the RCTRL register
should be zero-initialized, so just stop clearing it so that the setting
we applied in eth_ops :: set_promisc sticks.
