linux/generic: add MIB counters and port status to ADM6996 switch

Browse Source 
This patch adds port status information and MIB counters to the ADM6996
switch driver.

The driver supports also the older ADM6996L-variant, but I'm not able to
test this patch on that chip. According to the datasheet the same
registers exist there as well, so I think it should work, but any
feedback is appreciated.
