TMS320DM320: Add generic I/O debug window for targets other than mrobe 500.
DEBUG_GIO allows users to set any GIO options (direction, output state). As this feature should be used only by experienced users it is compiled conditionally. Raise I2C delay values since udelay() is now precise and previous values seems to be too low for some devices. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31421 a1c6a512-1295-4272-9138-f99709370657
