ARM: pxa: add U2D controller and ULPI driver for pxa3xx

USB2.0 Device Controller (U2DC) which is found in Marvell PXA3xx.
U2DC supports both High and Full speed modes.
PXA320 and PXA300 U2DC supports only UTMI interface.
PXA310 U2DC supports only ULPI interface and has the OTG capability.

U2D Controller ULPI driver introduced in this patch supports only the
PXA310 USB Host via the ULPI.
