====================
net: mdio-ipq4019: add Clause 45 support

This patch series adds support for Clause 45 to the driver.

While at it also change some defines to upper case to match rest of the driver.

Changes since v4:
* Rebase onto net-next.git

Changes since v1:
* Drop clock patches, these need further investigation and
no user for non default configuration has been found
