[PATCH] ARMV7: OMAP3: BeagleBoard: updated default configuration

* Decrease bootdelay to 3, use VGA for default resolution
* Add CONFIG_SYS_MEMTEST_SCRATCH to point to a scratch memory area.
* Enable LEDs
    Added LED driver using status_led. USR0 is set to monitor the boot
    status. USR1 is set to be the GREEN LED.
* Remove omapfb.debug=y from default env
* Add camera to default bootargs
* Move ramdisk parameters. This will make it easier to reprogram the ramdisk size.
* Improved boot env var setting
    * Enabled evaluation of expressions with 'setexpr'
    * Made room for a 64MB ramdisk by moving from 0x81600000 to 0x81000000
    * Removed expression from 'ramroot' that wouldn't be evaluated
    * Doubled console I/O buffer size from 256 to 512
    * Doubled maximum command arguments size from 16 to 32
* Enable multibus support for I2C
