145580388b ARM: pxa: export symbols from pxa3xx-ulpi 
The pxa3xx_u2d_start_hc/pxa3xx_u2d_stop_hc symbols are used by the
ohci-pxa27x driver, which can be a module.

a754aea25e ARM: pxa: fix pxa3xx-u2d crash when ULPI not used 
In case the pxa3xx-u2d driver isn't used, probing of ohci-pxa27x will cause an
ugly kernel crash (NULL pointer dereference in pxa3xx_u2d_start_hc(), because
struct u2d is NULL and clk_enable() call will crash the kernel, trying to access
it).

69f22be7b1 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.
