disable_port call. Remove it.

Add port_cleanup function to reset some device variables when the port is
disabled. Add a mutex to make sure changing those variables is
thread-safe.

Add background MIB counter reading support.
Port MIB counters should only be read when there is link. Otherwise it is
a waste of time as hardware never increases those counters. There are
exceptions as some switches keep track of dropped counts no matter what.

Break KSZ9477 DSA driver into two files in preparation to add more KSZ
switch drivers.
Add common functions in ksz_common.h so that other KSZ switch drivers
can access code in ksz_common.c.
Add ksz_spi.h for common functions used by KSZ switch SPI drivers.
