Merge branch 'cpsw-host_port' 

Grygorii Strashko says:

====================
drivers: net: cpsw: fix ale calls and drop host_port field from cpsw_priv

This clean up series intended to:
 - fix port_mask parameters in ale calls and drop unnecessary shifts
 - drop host_port field from struct cpsw_priv
====================
