Remove conversion from Big Endian to CPU order in the ads7846 driver.

OMAP1 was using STI_DR instead of STI_RX_DR, which was causing problems
in the RX path. OMAP2 has a consolidated XTI_TRACESELECT, the logic for
trace clearing is the logical inverse of the OMAP1 STI_DR, so fix that
while we're at it.

Clock framework specifies that the selection of clock should be
done based on the device id for similar clocks. This patch adds
support for MMC clocks. Clock device id handling adapted from
mach-s3c2410/clock.c.

Add error checking to clock functions

In the uWire driver only one of the clock dividers was used to set
the clock to the required frequency. This will add a loop to try all
possible combinations using the other divider as well.

- Support for the Philips LPH8923 LCD panel
- Support for the Epson HWA742 LCD controller

- Support for frame buffer located in SRAM and/or SDRAM
- Support for boot loader initialized LCD controller / frame buffer
  content.

- LCD panels will now register a device in the relevant board-* files
  instead of specifying the LCD type as an OMAP_TAG_LCD. The controller
  type is still specified in OMAP_TAG_LCD.
- A new ATAG OMAP_TAG_FBMEM is used to describe the frame buffer memory
  configuration (SRAM and SDRAM regions)

- Changed the OMAP1 LCD controller driver to export its functions
  through the lcd_ctrl object.
- OMAP1 pixel clock divider will now round up in lcdc.c
- Changed the OMAP1 SoSSI driver to export its functions through the
  lcd_ctrl_extif object.
- OMAP1 SoSSI clock calculation goes through all possible clock
  dividers. Rounding of clock tick values now takes places at each
  timing parameter.

- OMAP2 RFBI clock calculation goes through all possible clock
  dividers. Rounding of clock tick values now takes places at each

Avoid other SA_TRIGGER_* flags triggering BUG()

This implements a simple subsystem for the OMAP serial tracing interface,
as found in omap16xx and omap24xx.

There's a few things implemented in this patch:

        - STI console support
        - STI netlink support
        - STI RX FIFO support

In addition to this, we also provide a general tracing framework that can
be used by both the kernel and userspace (and imask control for allowing
DSP-side STI manipulation).

Since the IRQ is multiplexed, drivers register for the bits they're
interested in (the RX FIFO is an example of this).

The netlink interface exists for streaming data bi-directionally. This is
currently done using NETLINK_USERSOCK, which ends up being somewhat
limiting.

All of these things have been tested on both OMAP1 and OMAP2, and it
takes in to account some of the protocol differences.
