Instead of copying the whole platform data structure to struct
sh_mobile_lcdc_chan, store a const pointer to the channel platform data.
MERAM configuration information needs to be changed at runtime, so copy
it to struct sh_mobile_lcdc_chan.

Instead of manually specifying the ICBs to use in platform data,
allocate them automatically at runtime. The range of reserved ICBs (for
instance to be used through UIO), if any, is passed in the platform data
reserved_icbs field as a bitmask.
The MERAM registration function now returns a pointer to an opaque MERAM
object, which is passed to the update and unregistration functions.

The new structure stores ICB parameters for ICBs.
Instead of modifying the struct sh_mobile_meram_cfg instances passed by
callers, store the ICB parameters internally and make the public API
take const pointers to sh_mobile_meram_cfg.

The structure describe ICB configuration, no ICB objects themselves.
Rename it to sh_mobile_meram_icb_cfg in preparation for the addition of

Now that we have platform data contained within the individual board
code, we can get rid of the global function pointers, placing them
inside the platform data instead.

Samsung S5PC210 and EXYNOS SoC platform has MIPI-DSI controller and
MIPI-DSI based LCD Panel could be used with it. This patch supports
MIPI-DSI driver based Samsung SoC chip.
LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at
machine code and LCD panel driver specific function registered to
mipi_dsim_ddi structure at lcd panel init function called system init. In
the MIPI-DSI driver, find lcd panel driver by using registered lcd panel
name, and then initialize lcd panel driver.

A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.
