VPIF display changes (Chaithrika)

Add platform device and resource structures. Also define a platform specific
clock setup function that can be accessed by the driver to configure the clock
and CPLD.

VPIF caputure changes (Murali)

1) Modify vpif_subdev_info to add board_info, routing information and
   vpif interface configuration. Remove addr since it is part of
   board_info

2) Add code to setup channel mode and input decoder path for vpif
   capture driver

Also incorporated comments against version v0 of the patch series and
added a spinlock to protect writes to common registers

Tested on DM6467 on channel 0 using TVP514x. Following bootargs used
for drivers:

   vpif_capture.ch0_bufsize=829440 vpif_display.ch2_bufsize=829440

There is no need to pass clock name strings in platform_data.
Instead, setup clkdev nodes to have correct ASoC device names.

Controls ATA_RSTn and ATA_PWD through CPLD register 0 to enable ATA. An I2C
driver is added for the same. Calls ide init if enabled in configuration.

1) Registers the platform devices for ASP on dm355, dm644x and dm646x
   so that the machine driver can probe to get ASP related platform
   data.
2) Move towards definition of the asp clocks using physical name(for
   dm355 and dm644x)
3) Add platform data to board specific files.

Since most of the emac platform_data is really SoC specific
and not board specific, move it to the SoC-specific files.
Put a pointer to the platform_data in the soc_info structure
so the board-specific code can set some of the platform_data
if it needs to.

Create a structure to encapsulate SoC-specific information.
This will assist in generalizing code so it can be used by
different SoCs that have similar hardware but with minor
differences such as having a different base address.

The idea is that the code for each SoC fills out a structure
with the correct information.  The board-specific code then
calls the SoC init routine which in turn will call a common
init routine that makes a copy of the structure, maps in I/O
regions, etc.

After initialization, code can get a pointer to the structure
by calling davinci_get_soc_info().  Eventually, the common
init routine will make a copy of all of the data pointed to
by the structure so the original data can be made __init_data.
That way the data for SoC's that aren't being used won't consume
memory for the entire life of the kernel.

The structure will be extended in subsequent patches but
initially, it holds the map_desc structure for any I/O
regions the SoC/board wants statically mapped.
