Commit db97eb7d
(omap: gpmc: enable irq mode in gpmc) enabled interrupts for
GPMC (General Purpose Memory Controller). However, looks like
this patch only works on omap3. Fix the issues to avoid warnings
on omap4 during the boot.

GPMC: number of chip select is 8, CS0 to CS7. One less IRQ
allocated throws below warning at boot:

Adding DVI support to OMAP4 PandaBoard.

PandaBoard uses TFP410 DVI Framer chip
http://focus.ti.com/lit/ds/symlink/tfp410.pdf

The TFP410 gets its power enable and display data over GPIO lines muxed
in from OMAP4430. PandaBoard supports other LCD displays through
expansion
connectors, following board rework. This will disable the DVI interface.
However, the existing mux settings remain the same

PandaBoard additionally supports display over HDMI interface. It is
mutually exclusive to display over DVI. Hence the mux settings need to
be
configured seperately, as and when HDMI is enabled

Also, I2C3 bus used for reading EDID data from DVI Monitors is
registered here. Since the design is similar to BeagleBoard, the code
for the same is taken from the kernel.org commit e3333f48
(omap: Adding beagle i2c eeprom driver to read EDID)

The patch adds the new power management trace points for
the OMAP architecture.

The trace points are for:
- default idle handler. Since the cpuidle framework is
  instrumented in the generic way there is no need to
  add trace points in the OMAP specific cpuidle handler;
- SoC clocks changes (enable, disable, set_rate),
- power domain states: the desired target state and -if different-
  the actually hit state.

Because of the generic nature of the changes, OMAP3 and OMAP4 are supported.

Tested on OMAP3 with suspend/resume, cpuidle, basic DVFS.
