Commit Message

MediaTek moved some usb interface related function to btmtk.c which
may cause build failed if BT USB Kconfig wasn't enabled.
Fix undefined reference by adding config check.

btmtk.c:(.text+0x89c): undefined reference to `usb_alloc_urb'
btmtk.c:(.text+0x8e3): undefined reference to `usb_free_urb'
btmtk.c:(.text+0x956): undefined reference to `usb_free_urb'
btmtk.c:(.text+0xa0e): undefined reference to `usb_anchor_urb'
btmtk.c:(.text+0xb43): undefined reference to `usb_autopm_get_interface'
btmtk.c:(.text+0xb7e): undefined reference to `usb_autopm_put_interface'
btmtk.c:(.text+0xf70): undefined reference to `usb_disable_autosuspend'
btmtk.c:(.text+0x133a): undefined reference to `usb_control_msg'
