4af0d7e870 dm: Fix up inclusion of common.h
It is good practice to include common.h as the first header. This ensures
that required features like the DECLARE_GLOBAL_DATA_PTR macro,
configuration options and common types are available.

Fix up some files which currently don't do this. This is necessary because
driver model will soon start using global data and configuration in the
dm/read.h header file, included via dm.h. The gd->fdt_blob value will be
used to access the device tree and CONFIG options will be used to
determine whether to support inline functions in the header file.

a821c4af79 dm: Rename dev_addr..() functions
These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.

e160f7d430 dm: core: Replace of_offset with accessor
At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

bb5930d5c9 exynos: video: Convert several boards to driver model for video
Update several boards to use driver model for video. This involves changes
to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and
pwm-backlight drivers are used. These work without additional configuration
since they use the device tree settings in the same way as Linux.

Boards converted are:
- snow
- spring
- peach-pit
- peach-pi

All have been tested. Not converted:

- MIPI display driver
- s5pc210_universal
- smdk5420
- smdk5250
- trats
- trats2

21f8f9bb08 exynos: video: Rename edp_device_info to exynos_dp_priv
Rename this function to better fit with driver model. It is the private data
for the exynos EDP driver.

7eb860df13 exynos: Simplify calling of exynos_dp_phy_ctrl()
This function controls enabling the EDP PHY. Rename it and drop the existing
weak functions, which are confusing.
