Rather than passing the platform device to the ->init() and ->exit()
methods, make these methods useful for other devices by passing the
struct device instead. Update the implementations appropriately for
this change.

Move the calls for these methods into the core driver's probe and
remove methods from the stmmac_platform layer.

Convert dwmac-rk to use ->init() and ->exit().

As struct plat_stmmacenet_data is not platform_device specific, pass
a struct device into the init() and exit() methods to allow them to
become independent of the underlying device.

* [PATCH net-next 1/3] net: stmmac: pass struct device to init()/exit() methods

As struct plat_stmmacenet_data is not platform_device specific, pass
a struct device into the init() and exit() methods to allow them to
become independent of the underlying device.

* [PATCH net-next 1/3] net: stmmac: pass struct device to init()/exit() methods

As struct plat_stmmacenet_data is not platform_device specific, pass
a struct device into the init() and exit() methods to allow them to
become independent of the underlying device.

Move the probe/remove time calling of the init()/exit() methods in
the platform data to the main driver probe/remove functions. This
allows them to be used by non-platform_device based drivers.
