fbdev: omap2: connector-dvi: use of_get_i2c_adapter_by_node interface

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

This change is needed to properly lock I2C bus driver, which serves DDC.

Prior to this change i2c_put_adapter() is misused, which may lead to
an overflow over zero of I2C bus driver user counter.
