Subject: Add a backend for Silicon Labs CP2110/4 HID-to-UART bridge.

These two chips implement UART access via a HID protocol, which can be
implemented purely in user space. The protocol is documented by Silicon
Labs AN434:
https://www.silabs.com/documents/public/application-notes/AN434-CP2110-4-Interface-Specification.pdf

The backend is implemented based on cython-hidapi
(https://github.com/trezor/cython-hidapi), making it OS-independent, if a
bit awkward.
