Subject: [PATCH 04/12] net: phy: unify get_phy_device and phy_device_create
 parameter list

Currently these two public APIs are used to create a 'struct phy_device'
device. In addition to that the device get_phy_device() can adapt the
is_c45 parameter as well if supprted by the mii bus.

Both APIs do have a different set of parameters which can be unified to
upcoming API extension. For this the 'struct phy_device_config' is
introduced which is the only parameter for both functions. This new
mechnism also adds the possiblity to read the configuration back within
the driver for possible validation checks.
