====================
introduce generic phylink validation

The various validate method implementations we have in phylink users
have been quite repetitive but also prone to bugs. These patches
introduce a generic implementation which relies solely on the
supported_interfaces bitmap introduced during last cycle, and in the
first patch, a bit array of MAC capabilities.

MAC drivers are free to continue to do their own thing if they have
special requirements - such as mvneta and mvpp2 which do not support
1000base-X without AN enabled. Most implementations currently in the
kernel can be converted to call phylink_generic_validate() directly
from the phylink MAC operations structure once they fill in the
supported_interfaces and mac_capabilities members of phylink_config.

This series introduces the generic implementation, and converts mvneta
and mvpp2 to use it.
