928c4bdf9b usb: ulpi: Add omap-ulpi-view port support
Based on discussion from this thread [1].
Adding omap-view port that helps us in using the generic ulpi
framework for any ulpi phy ops using the INSNREG05_ULPI viewport
reg available on omap platform.

Currently ehci ports are available on omap3/4 platforms so enable the same
for beagle and panda, patch is tested on the same boards.

Thanks to Igor Grinberg <grinberg@compulab.co.il> for reviewing the
omap-ehci patches and suggesting this approach.

There is no benefit in using u8, so switch to unsigned to reduce the
binary image size (by 20 bytes).
