This is a forward port of the DaVinci framebuffer driver (originally
written by TI) from the MV 2.6.10 kernel.  It consists primarily of a
rework to the newer driver model and a rework of the debug printks.
No code has been changed or reorganized.

Add basic gpio operations:  get value, set/clear, set direction, and
use gpio as an irq.  Includes irq and clock cleanups, but no muxing
updates (e.g. PINMUX0/PINMUX1 declarations).

Lightly tested; gpio outputs seem to behave, as do IRQs in banks 0 and 2.
The issue with banks 1, 3 and 4 may be just not having found a pin that's
not muxed to some essential purpose, for testing.

The recent MPUIO range change fix breaks compilation if
CONFIG_ARCH_OMAP24XX isn't defined; it should be OMAP_MAX_GPIO_LINES not
MAX_GPIO_LINES I believe. This one liner fixes it.

This patch adds some further #defines regarding GPIOs and latch bits for

(cherry picked from 64929d88 commit)

Add support for assigning memory regions dynamically to peripherals
attached to GPMC interface. Platform specific code should now call
gpmc_cs_request to get a free GPMC memory region instead of using
a fixed address.

Make the H4 and Apollon platform initialization use the new API.

Some things are probably broken right now with the generic irq
code update.

Since ab7ad9fe sti-console puts
crap into STI if serial console is configured as a preferred console.

This is due to uninitialized sti_console_channel (0 is a bad channel
value).

The fix is to check the STI channel value before registering the
console driver.
