usb: gadget: rename CONFIG_USB_GADGET_PXA25X

commit d30f2065 upstream.

Commit 193ab2a6 ("usb: gadget: allow multiple gadgets to be built")
basically renamed the Kconfig symbol USB_GADGET_PXA25X to USB_PXA25X. It
did not rename the related macros in use at that time. Commit
c0a39151 ("ARM: pxa: fix inconsistent CONFIG_USB_PXA27X") did so for
all but one macro. Rename that last macro too now.
