generic: drop support for get_port_stats() on ar8xxx
The implementation is not efficient on ar8xxx switches. It triggers high
CPU load and degrades device performance.
The high CPU load has been traced down to the ar8xxx_reg_wait() call in
ar8xxx_mib_op(), which has to usleep_range() till the MIB busy flag set
by the request to update the MIB counter is cleared.
This commit removes the get_port_stats() code introduced in 4d8a66d and
leaves a note for future hacker's beware.
Fixes: FS#1004
