usb: gadget: Mark USB_FSL_QE broken on 64-bit
On 64-bit:
drivers/usb/gadget/udc/fsl_qe_udc.c: In function ‘qe_ep0_rx’:
drivers/usb/gadget/udc/fsl_qe_udc.c:842:13: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
842 | vaddr = (u32)phys_to_virt(in_be32(&bd->buf));
| ^
In file included from drivers/usb/gadget/udc/fsl_qe_udc.c:41:
drivers/usb/gadget/udc/fsl_qe_udc.c:843:28: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
843 | frame_set_data(pframe, (u8 *)vaddr);

The driver assumes physical and virtual addresses are 32-bit, hence it
cannot work on 64-bit platforms.
