Hi David,

In the previous patch, there's some changes in UDC.
It makes the apollon USB can't work.
After some work, I found that you changed the double-buffering condition. It breaks the apollon behavior.

Please append apollon board condition when we use the pio mode, then don't use double-buffering.
and also fix some compiler warning

ARM: OMAP: fix apollon USB device support

	- Add apollon use the non-double-buffering in PIO mode
	- fix compiler warning
