[U-Boot] [PATCH] usb: omap: ulpi: fix ulpi reading/writing functions

[Michael Trimarchi <michael@amarulasolutions.com>]

Fix ulpi reading and writing function.
 * Both functions need to have the bit31 setted.
 * Right now uboot use 0 to enumerate port 1 and 1 to
   enumerate port 2 and so on. Omap code use 1 for port 1 and 2 for port 2.
   Add a +1 fix the problem
