MDIO controller on little endian Socs, e.g. ls2085a is similar to the
controller on big endian Socs, but the MDIO access is little endian,
we use I/O accessor function to handle endianness, so the driver can
run on little endian Socs. A property "little-endian" is used
in DTS to indicate the MDIO is little endian, if driver probes the
property, driver will access MDIO in little endian, otherwise, driver
works in big endian by default.

There is a bug in xgmac_wait_until_done() which mdio_stat should be used
instead of mdio_data when checking if busy bit is cleared.

The Freescale mEMAC supports operating at 10/100/1000/10G, and
its associated MDIO controller is likewise capable of operating
both Clause 22 and Clause 45 MDIO buses. It is nearly identical
to the MDIO controller on the XGMAC, so we just modify that
driver.

There is no need to set the clock speed in read/write which will be performed
unnecessarily for each mdio access. Init it during probe is enough.
Also, the hardcoded clock value is not a proper way for all SoCs.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.
Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.
