Subject: [patch] Add IVB model 3e support to /drivers/idle/intel_idle.c

Hi, Len
    Please help to review and apply the patch if it is OK.
I didn't go through all the related code, simply add the model 3e to
the id list, I have tested it with stable branch kernel 3.6.7 on my
Server with Intel ES0 installed.

Thanks,
Ethan
