This series contributes to cleaning up phylib by moving PHY package
related code to its own source file.

v2:
- rename the getters
- add a new header file phylib.h, which is used by PHY drivers only
v3:
- include phylib.h in bcm54140.c

Heiner Kallweit (8):
  net: phy: move PHY package code from phy_device.c to own source file
  net: phy: add getters for public members in struct phy_package_shared
  net: phy: qca807x: use new phy_package_shared getters
  net: phy: micrel: use new phy_package_shared getters
  net: phy: mediatek: use new phy_package_shared getters
  net: phy: mscc: use new phy_package_shared getters
  net: phy: move PHY package related code from phy.h to phy_package.c
  net: phy: remove remaining PHY package related definitions from phy.h

This patch is the first step in moving the PHY package related code
to its own source file. No functional change intended.

Add getters for public members, this prepares for making struct
phy_package_shared private to phylib. Declare the getters in a new header
file phylib.h, which will be used by PHY drivers only.

Move definition of struct phy_package_shared to phy_package.c, and
move remaining PHY package related declarations from phy.h to
phylib.h, thus making them accessible for PHY drivers only.
