Subject: [PATCH] gmux: Fix backlight set function

In commit 7e30ed6b, "gmux: Add generic write32 function", the new
gmux_write32() function didn't include the io offset when writing
registers. This means that backlight update writes never go to the right
place. This patch fixes it.

Tested on Apple Macbook 8,3
