device: combine debug and info log levels into 'verbose'
There are very few cases, if any, in which a user only wants one of these levels, so combine it into a single level. While we're at it, reduce indirection on the loggers by using an empty function rather than a nil function pointer. It's not like we have retpolines anyway, and we were always calling through a function with a branch prior, so this seems like a net gain. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
