This patch series does three things: 1) Adds an implementation of the OpenTitan Always-On Timer's watchdog functionality 2) Fixes a bug encountered with the SiFive PLIC device during development 3) Updates the register addresses and adds support for writes to mtime for the Ibex timer
(2) is necessary for the bark interrupt to work. (3) will bring the Ibex timer up to spec.
