This UIO driver was used to control the PRU processors found on various
TI SoCs. It was created before the Remoteproc framework, but now with
that we have a standard way to program and manage the PRU processors.
The proper PRU Remoteproc driver should be used instead of this driver.
This driver only supported the original class of PRUSS (OMAP-L1xx /
AM17xx / AM18xx / TMS320C674x / DA8xx) but when these platforms were
switched to use Device Tree the support for DT was not added to this
driver and so it is now unused/unusable. Support for these platforms
can be added to the proper PRU Remoteproc driver if ever needed.
Remove this driver.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Remove the use of the private DaVinci SRAM API in favor
of genalloc. The pool to be used is provided by platform
data.

This patch implements PRUSS (Programmable Real-time Unit Sub System)
UIO driver which exports SOC resources associated with PRUSS like
I/O, memories and IRQs to user space. PRUSS is dual 32-bit RISC
processors which is efficient in performing embedded tasks that
require manipulation of packed memory mapped data structures and
handling system events that have tight real time constraints. This
driver is currently supported on Texas Instruments DA850, AM18xx and
OMAP-L138 devices.
For example, PRUSS runs firmware for real-time critical industrial
communication data link layer and communicates with application stack
running in user space via shared memory and IRQs.
