This patch fixes the OMAP4430 cpu detection. The IC rev detection is
done with hawkeye and rev. Note that rev does not map directly to
defined processor revision numbers as ES1.0 uses value 0.It also fixes
the SCM base address to read the correct ID_CODE register.

Also the cpu_is_omap44xx() and cpu_is_omap443x() correctly populated
instead of always being true

Pandora board file updates:
- change keycodes of game buttons
  it was decided not to use ABXY layout by the developers.
- drop i2c bus 3 speed to 100kHz
  this is needed for battery monitoring chip to work reliably.
- drop pandora_lcd platform_device
  the older DSS driver was never functional on l-o or mainline
  kernels due to missing panel driver, so remove unneeded
  pandora_lcd platform_device. This also removes last OMAP_TAG
  from the board file.

Add new style mux data for 34xx. This should also

Note that this data is __initdata, and gets optimized
out except for the GPIO pins if CONFIG_OMAP_MUX
is not set.

Also note that this data uses omap3630 naming for
the SDMMC registers instead of 34xx naming with just
MMC.

Initially only for 34xx. This code allows us to:

- Make the code more generic as the omap internal signal
  names can stay the same across omap generations for some
  devices

- Map mux registers to GPIO registers that is needed for
  dynamic muxing of pins during off-idle

- Override bootloader mux values via kernel cmdline using
  omap_mux=some.signa1=0x1234,some.signal2=0x1234

- View and set the mux registers via debugfs if
  CONFIG_DEBUG_FS is enabled

Earlier, the hwmod code had considered the OCP_SYSCONFIG.CLOCKACTIVITY
bits to be incremental power saving bits, controlling internal IP
block clock gates.  This was a misapprehension.  The CLOCKACTIVITY
bits are used to indicate, in advance, which clocks will be cut when
the module acknowledges an idle request.  This enables the IP block to
take whatever action is necessary to complete any in-progress work
before asserting its IdleAck.

In the current Linux-OMAP code, this implies that the clock framework
should be changing module CLOCKACTIVITY bits as module clocks are enabled
and disabled.  We don't do that yet, but in the future, we should.
This must wait until the clock tree is annotated with omap_hwmod pointers
(or vice-versa).  In the meantime, drop most of the hwmod code that
controls CLOCKACTIVITY bits to avoid confusion.

This patch has benefited from many illuminating discussions with (in
alphabetical order) Benoît Cousson <b-cousson@ti.com>, Rajendra Nayak
<rnayak@ti.com>, and Sebastien Sabatier <s-sabatier1@ti.com>.

Replace the existing u8 array of module MPU IRQ lines with a struct
that includes a name - similar to the existing struct
omap_hwmod_dma_info.  Device drivers can then use
platform_get_resource_byname() to retrieve specific IRQs without nasty
dependencies on array ordering.

This patch fills in the OCP_SYSCONFIG.AUTOIDLE handling in the OMAP
hwmod code.

After this patch, the hwmod code will set the module AUTOIDLE bit
(generally <module>.OCP_SYSCONFIG.AUTOIDLE) to 1 by default upon
enable.  If the hwmod flag HWMOD_NO_OCP_AUTOIDLE is set, AUTOIDLE will
be set to 0 upon enable.  Upon module disable, AUTOIDLE will be set to
1.

Enabling module autoidle should save some power.  The only reason to
not set the OCP_SYSCONFIG.AUTOIDLE bit is if there is a bug in the
module RTL, e.g., the MPUINTC block on OMAP3.
