net: phy: add support for PHY package MMD read/write
Some PHY in PHY package may require to read/write MMD regs to correctly
configure the PHY package.
Add support for these additional required function in both lock and no
lock variant.
It's assumed that the entire PHY package is either C22 or C45. We use
C22 or C45 way of writing/reading to mmd regs based on the passed phydev
whether it's C22 or C45.
