Subject: [PATCH net-next 1/5] net: mdio-gpio: Localize platform data

It is late on the day for platforms using platform data to pass
information to drivers. As of today, the only thing in the kernel
including the <linux/platform_data/mdio-gpio.h> file is the MDIO
GPIO driver itself.

Essentially it is exposing a kernel-internal interface unused by
any in-kernel code.

Let's decomission this and make the MDIO GPIO driver more
self-contained by starting to move this struct into the driver.

Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
