net: phy: add PHY package locking helpers

The PHY package API provides private data shared by all PHYs in a
package. Drivers are responsible for synchronizing access to this data,
but the API does not provide a lock for that purpose.

Add phy_package_lock() and phy_package_unlock() for drivers to serialize
access to package-private data, including its initialization.
