ENGR00275483-2 mxc fb: port mipi dsi drivers from 3.0.35 to 3.10

This patch is a fastforward porting for mipi dsi driver and
TRULY-WVGA mipi panel driver.
* Add devicetree support for the mipi dsi driver.
* Get mipi config clock source in the mipi dsi driver.
* Change clk_enable()/clk_disable() to clk_prepare_enable()/
  clk_disable_unprepare().
* Move mipi dsi driver initialization stuff to mipi_dsi_probe()
  from mipi_dsi_disp_init().
* Move mach/mipi_dsi.h to linux/mipi_dsi.h.
* Remove __devexit_p and __devexit since 3.10 kernel doesn't
  support them.
* Remove struct mipi_dsi_platform_data from mach/mipi_dsi.h.
* Remove mach/hardware.h, mach/clock.h, linux/fsl_device.h
  and linux/regulator/consumer.h in the drivers.
* Remove special pixel clock setting for imx6sdl since no
  issue is found without it.
* Remove unused reset, lcd_power and backlight_power interfaces
  in struct mipi_dsi_info.
* Remove unused regulator related entries in struct mipi_dsi_info.
* Remove the IOMUX_GPR3_OFFSET macro from mipi dsi driver since
  the muxing is done with common regmap APIs.
* Rename ipu_id to dev_id since i.MX6DL RM tells that lcdif can
  connect with mipi dsi.
* Add mipi dsi related information in the devicetree binding
  documentation.
