Also tested with 2.6.35-23-omap

Test environment:
Linux ubuntu 2.6.35-23-omap #37-Ubuntu Sat Nov 6 02:01:12 UTC 2010
armv7l GNU/Linux
ubuntu@ubuntu:~$ cat /proc/version
Linux version 2.6.35-23-omap (buildd@gourd) (gcc version 4.4.5
(Ubuntu/Linaro 4.4.4-14ubuntu5) ) #37-Ubuntu Sat Nov 6 02:01:12 UTC
2010

Test case 1 : Check VMMC2 regulator is not enabled on boot
  - Step 1 : Boot an IGEP v2 board with this patch
  - Step 2: Check for active regulators.
     dmesg | grep regulator
     [ 0.000000] regulator: core version 0.5
     [ 0.012847] regulator: VUSB1V5: 1500 mV normal standby
     [ 0.013153] regulator: VUSB1V8: 1800 mV normal standby
     [ 0.013427] regulator: VUSB3V1: 3100 mV normal standby
     [ 0.015533] regulator: VMMC1: 1850 <--> 3150 mV at 3000 mV
normal standby
     [ 0.015838] regulator: VDAC: 1800 mV normal standby
     [ 0.016204] regulator: VDVI: 1800 mV normal standby
 - Result : PASS VMMC2 regulator is not active.

Note: On IGEP v2 the device connected to MMC2 bus uses another
dedicated regulator instead of VMMC2, so it's safe disable this
regulator.
