LS_OE GPIO was changed from gpio6_28 to gpio2_30 for the Rev B1 board,
and the current .dts file has the old GPIO.
Rev B1 is the earliest board supported, so we can just change the .dts.
This fixes "omapdss error: HDMI I2C Master Error" which causes failure
to read EDID from the monitor.

I believe we have A2s being shipped as well. we dont want to break A2s
either -> I propose we refactor the dts to introduce revb1 X15.
There are at-least 200 A2's that have been shipped to end users.

Thanks. Tomi: if you are ok - I already do have a refactoring code
from older kernel. I will rebase to latest and repost.
Tony: is there a branch youd' like me to base the changes on?
