arch/arm/src/common/stm32: accept interface-recipient GET/SET_DESCRIPTOR
HID class devices fetch the HID Report Descriptor with a
GET_DESCRIPTOR setup packet whose recipient is an interface
(bmRequestType 0x81, wValue 0x2200). stm32_ep0out_stdrequest() only
dispatches device-recipient descriptor requests and stalls the rest,
so HID class devices cannot enumerate. Dispatch interface-recipient
requests to the class driver as well.
