[patch] htc hermes update

Hi,

The attached patch updates the HTC Hermes code. It adds support for
the egpio chip, side buttons, vibra/flashlight/kbd-backlight, and usb
detect.

I've also added in (but have not enabled) support for the "bbkeys"
driver which controls the front keypad, front leds, and lcd power. I
have it disabled because it is not yet working and I'm still trying to
figure out why.

I have also disabled the nand driver - in its current state it just
spams the console with lots of "bad block" messages.

Also, even with this patch, the phone is drops usbnet irqs and seems
to run hot when in linux. This existed previously, so it is not a
regression.

Finally, note that this patch requires the s3c gpiodev2 and pxa
gpio_direction_output patches I just sent.

Cheers,
-Kevin
