From: Arınç ÜNAL <arinc.unal@arinc9.com>

There's no need to clear the config->supported_interfaces bitmap before
reporting the supported interfaces as all bits in the bitmap will already
be initialized to zero when the phylink_config structure is allocated. The
"config" pointer points to &dp->phylink_config, and "dp" is allocated by
dsa_port_touch() with kzalloc(), so all its fields are filled with zeroes.

There's no code that would change the bitmap beforehand. Remove it.
