[U-Boot] [PATCH] BeagleBoard: Pin mux initialization glitch fix

[Jason Kridner]

From: Bob Feretich <bob.feretich at rafresearch.com>

The below patch reverses the order of two segments in the board file.
Output pins need to have their values initialized, before they are
exposed to the logic outside the chip.
