[PATCH next] usb: mtu3: fix build error caused by dev_xxx()

[Chunfeng Yun]

Due to the following to patches:
4a1989c0bc77 ("dm: Don't undefine dev_xxx macros")
69dae8902b16 ("linux/compat.h: Remove redefinition of dev_xxx macros")

Need include device_compat.h and no need use __maybe_unused anymore
to fix unused variable warning

Please squash in: ab703ebb1cc0 ("usb: add MediaTek USB3 DRD driver")
in u-boot-usb/next

Sorry for inconvenience
