Subject: [PATCH v3 1/4] usb: xhci-mtk: use bitfield instead of bool

Use bitfield instead of bool in struct

Refer to coding-style.rst 17) Using bool:
"If a structure has many true/false values, consider consolidating
them into a bitfield with 1 bit members, or using an appropriate
fixed width type, such as u8."
