Subject: [PATCH] USB: serial: ch341: add register and USB request definitions

commit 6fde8d29b0424f292a4ec5dbce01458ad759a41f upstream.

No functional changes, this just gives names to some registers and USB
requests based on Grigori Goronzy's work and WinChipTech's Linux driver
(which reassuringly agree), then uses them in place of magic numbers.
This also renames the misnamed BREAK2 register (actually UART config)
