Currently the sh_mobile_lcdc driver only reconfigures the hardware interface,
when a new monitor is plugged in. This patch adds support for dynamic
framebuffer reconfiguration, when no user is holding the framebuffer device
node open.

Current touchpanel had below 2 issues

- LCDD2 pin which is needed for WVGA was changed to
  IRQ28_123 pin on ts_get_pendown_state

- GPIO pull up on ts_init was disabled by gpio_request
  on ts_get_pendown_state.
  This mean the return value from gpio_get_value is untrusted.

This patch solve these issues

With this patch hot-plugging of an HDMI or a DVI monitor can select a different
video mode and reconfigure the LCDC and HDMI controllers accordingly. Due to a
lack of a standard API to inform framebuffer users of a changed video mode, the
framebuffer configuration is preserved regardless of a specific mode, selected
for the monitor. As described in a previous patch, this leads to smaller
framebuffers being displayed on larger monitors or a part of a larger
framebuffer being displayed on a smaller resolution monitor.

The SH-Mobile HDMI driver runs in several contexts: ISR, delayed work-queue,
task context, when called from the sh_mobile_lcdc framebuffer driver. This
creates ample race possibilities. Even though most these races are purely
theoretical, it is better to close them. To trace fb_info validity we install a
notification callback in the HDMI driver, and the only way for it to get to
driver internal data is by using struct sh_mobile_lcdc_chan, therefore it had
to be extracted into a separate common header.

The SH-Mobile HDMI controller supports two configuration modes: using
pre-programmed VICs and the "external" mode - specifying video parameters
explicitly. The driver already contains code, necessary to configure HDMI
manually, this patch actually enables it.

This is a preparation for HDMI hotplug support. This patch just moves all
platform defined video modes for the sh_mobile_lcdcfb driver to separate
arrays and switches all users to use element 0 of that array, so, this patch
doesn't introduce any functional changes and as such should not cause any
regressions.

This patch fixes the following two erroneous error paths:

hw_usecnt is allocated with a value of 0, therefore in an early error case,
calling sh_mobile_lcdc_clk_off() will wrongly conclude, that hw_usecnt has
already been incremented. Then sh_mobile_lcdc_runtime_suspend() will be called,
which will access uninitialised data fields and crash the kernel.

sh_mobile_lcdc_stop() can be called before framebuffer has been allocated, then
ch->info is NULL and dereferencing it will Oops too.

The present SH-Mobile HDMI driver reads and parses the EDID block into a
variable screeninfo object, but since it is still unable to dynamically
reconfigure the framebuffer, it overwrites the EDID information with preset

timing information instead.

Mathieu reported bad latencies with make -j10 kind of kbuild
workloads - which is mostly caused by us scheduling with a
too coarse granularity.

Reduce the minimum granularity some more, to make sure we
can meet the latency target.

I got the following results (make -j10 kbuild load, average of 3
runs):

 vanilla:

  maximum latency: 38278.9 µs
  average latency:  7730.1 µs

 patched:

  maximum latency: 22702.1 µs
  average latency:  6684.8 µs

Mathieu also measured it:

|
| * wakeup-latency.c (SIGEV_THREAD) with make -j10
|
| - Mainline 2.6.35.2 kernel
|
| maximum latency: 45762.1 µs
| average latency: 7348.6 µs
|
| - With only Peter's smaller min_gran (shown below):

| maximum latency: 29100.6 µs
| average latency: 6684.1 µs
