This change defines all possible "IR schemes" related to the pvrusb2

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

V4L/DVB (11611): soc-camera: link host drivers after clients
With the transition of soc-camera to become a platform driver and to the
v4l2-subdev framework the initialisation order becomes important. In case
of a static build clients (i2c) drivers have to be available when host
drivers are probed. Moving host drivers down in the Makefile achieves the
desired order.
Embed struct soc_camera_host in platform-specific per host instance objects
instead of allocating them statically in drivers, use platform_[gs]et_drvdata
consistently, use resource_size().
V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_link
Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.
