Ian Lepore	8fb0ef085c	Enhance the interrupt capabilities of ti_pruss driver. The existing ti_pruss driver for the PRUSS Hardware provided by the AM335x ARM CPU has basic interrupt capabilities. This updated driver provides some more options: - Sysctl based configuration for the interrupts (for some examples, see the test plan in the phabricator review cited below). - A device file (/dev/pruss0.irqN) for each enabled interrupt. This file can be read and the device blocks if no irq has happened or returns an uint64_t timestamp based on nanouptime(). - Each interrupt device file provides kqueue-based event notification, blocking read(), or select().

Enhance the interrupt capabilities of ti_pruss driver.

The existing ti_pruss driver for the PRUSS Hardware provided by the AM335x
ARM CPU has basic interrupt capabilities.  This updated driver provides some
more options:

 - Sysctl based configuration for the interrupts (for some examples, see the
   test plan in the phabricator review cited below).

 - A device file (/dev/pruss0.irqN) for each enabled interrupt. This file
   can be read and the device blocks if no irq has happened or returns an
   uint64_t timestamp based on nanouptime().

 - Each interrupt device file provides kqueue-based event notification,
   blocking read(), or select().

Add a driver for the TI Programmable Realtime Unit Subsystem.

This is only a userland accessibility driver.  It mmaps the hardware region to
userland and posts interrupt notifications via kqueue.
