i2c-nomadik: turn the platform driver to an amba driver
The i2c-nomadik gateware is really a PrimeCell APB device. By hosting
the driver under the amba bus we can access it more easily, for
example using the generic pci-amba driver. The patch also fixes the
mach-ux500 users, so they register an amba device instead than a
platform device.
