Unfortunately, the asynchronous control request data stage validation
mechanism must be implemented by every UDC. This patch series only addresses
MUSB as this is Paul's main test platform. Once the core patches get reviewed
and the API accepted (possibly in a modified form), we plan to update the DWC2
and DWC3.
