Subject: [PATCH 12/32] usb: gadget: udc: lpc32xx_udc: Staticify 2 local functions

These are not used outside of this sourcefile, so make them static.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/gadget/udc/lpc32xx_udc.c:1929:6: warning: no previous prototype for ‘udc_send_in_zlp’ [-Wmissing-prototypes]
 1929 | void udc_send_in_zlp(struct lpc32xx_udc *udc, struct lpc32xx_ep *ep)
 | ^~~~~~~~~~~~~~~
 drivers/usb/gadget/udc/lpc32xx_udc.c:1943:6: warning: no previous prototype for ‘udc_handle_eps’ [-Wmissing-prototypes]
 1943 | void udc_handle_eps(struct lpc32xx_udc *udc, struct lpc32xx_ep *ep)
 | ^~~~~~~~~~~~~~
