This change adds support for HSA devices, which are
DMA devices that have an HSA packet processor (HSAPP).
An HSA packet processor model is also included. The
HSAPP is a DMA device that matains AQL packet queues
and handles extraction of AQL packets, scheduling
of AQL queues, and initiates kernel launch for HSA
devices.
Because these devices directly interact with low-level
software and aid in the implementation of the HSA ABI
we also include some headers from the ROCm runtime:
the hsa.h and kfd_ioctl.h headers. These aid with
support ROCm for the HSA devices and drivers.
