ARM: pxa/gumstix: fix attaching properties to vbus gpio device

Commit f1d6588af93b tried to convert GPIO lookup tables to software
properties for the vbus gpio device, bit forgot the most important
step: actually attaching the new properties to the device.

Also fix up the name of the property array to reflect the board name,
and add missing gpio/property.h and devices.h includes absence of which
causes compile failures on some configurations.

Switch "#ifdef CONFIG_USB_PXA25X" to "#if IS_ENABLED(CONFIG_USB_PXA25X)"
because it should not matter if the driver is buolt in or a module, it
still need vbus controls.
