An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling,
eliminating the need for an external transceiver to handle the level
shifting. This patch detects whether an external transceiver is present
and adjusts the pinmux settings as appropriate.

Confiures GPMC timings for both chips and also configures pinmux
for GPIO_65, which is used as the interrupt signal for the second chip

The latest Overo COM modules encode their revision number on
GPIOs 115, 113, and 112. All boards to date have no pullups on these pins
and hence appear as revision 0.
This patch reads and prints the revision information.

Use appropriate GPMC timings for the LAN9221 controller on the
Gumstix Overo expansion boards not the values in arch-omap3/mem.h
which are for a different ethernet controller.

Not all boards have both LEDs hooked, so enabling both on
boards with single LED will just waste power. Make it
possible to choose LEDs by adding argument to
twl4030_led_init().
Using this turn on only LEDB for pandora, leave both LEDs
on for all other boards, as it was before this patch.

Add setup for ethernet on Tobi, allowing kernel/ramdisk to be loaded
over tftp.
This also refactors the smc911x driver to allow for detecting when the
chip is missing. I.e. the detect_chip() function is called earlier and
will abort gracefully when the Chip ID read returns all 1's.
