Rakesh Goyal f71600879c nvethernet: Reset MAC registers on interface down and up. ...

Issue: MAC registers are not getting reset on ether_close(),
which lead to old values in MAC registers at the time of
osi_hw_core_init().

Fix: Assert MAC-RST gpio and disable clocks in ether_close().
Enable clock, reset MAC_RST gpio and poll for swr, which will
reset all MAC registers.

Note: To read MAC registers, you must have clocks enable and MAC
out of reset
