udc: lpc32xx: fix 64-bit compiler warning
gcc points out a suspicious cast from a pointer to an 'int' when compile-testing on 64-bit architectures. drivers/usb/gadget/udc/lpc32xx_udc.c: In function ‘udc_pop_fifo’: drivers/usb/gadget/udc/lpc32xx_udc.c:1156:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] drivers/usb/gadget/udc/lpc32xx_udc.c: In function ‘udc_stuff_fifo’: drivers/usb/gadget/udc/lpc32xx_udc.c:1257:11: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] The code works find, but it's easy enough to change the cast to a uintptr_t to shut up that warning.
