asmc driver patch file

Add support for MacBookPro6,2 (Mid 2010, 15") to asmc driver.
Ignores interrupt from ambient light sensor (referred to as ALSL from what I
could find).
Adds the number of an unknown interrupt to the log output.

First patch submission. Please let me know if I should change/fix anything.

The reason I choose to ignore the interrupt is that it triggers so often it
fills the logs/console with messages; I am not aware of how to determine if the
light levels are going up or down to make it useful; if this interrupt exists
on other models, I didn't see any code for it; and this interrupt does not
trigger on a MacBookPro9,2 that I tested the original asmc driver against. I'm
pretty sure it is specific to this model.
