Add a serial driver for the SiFive UART, found on SiFive FU540 devices
(among others).

The underlying serial IP block is relatively basic, and currently does
not support serial break detection.  Further information on the IP
block can be found in the documentation and Chisel sources:

https://static.dev.sifive.com/FU540-C000-v1.0.pdf

This driver was written in collaboration with Wesley Terpstra
[off-list ref].

Boot-tested on a SiFive HiFive Unleashed A00 board.

Seems like the 0-day bot did not like this driver, can you fix up those
build errors and resend?

thanks,
