This patch series enable accumulator queue support for K2 SoCs. Accumulator
queues are a type of qmss queue that is monitored by the PDSP firmware and
accumulated. Host is interrupted by PDSP firmware when packets become
available in a ring buffer shared between the host and PDSP.

There was an issue raised when merging the original patch set at
(1) https://lkml.org/lkml/2015/9/4/681
[PATCH v1 1/2] soc: ti: display firmware file name as part of boot log
(2) https://lkml.org/lkml/2015/9/4/680
[PATCH v1 2/2] ARM: dts: keystone: enable accumulator channels

This series fixes the issues raised against v3. Maintainer, could you please
apply this series to v4.4 next please at your earliest opportunity.

Change Log
==========
v4
- collected Acked-by from Arnd Bergmann against 1/3
v3
- Added Arnd's Acked-by against 2/4
- 1/4 modified not to touch the DT documentation per Rob's comment.
- Removed DTS update from the series per Santosh. Will send the same
as a separate patch
v2
- Remove the firmware filename from DT and add it to the driver.
Use a name ks2_qmss_pdsp_acc48.bin. The idea is this can be a
soft link pointing to the real firmware file in file system.

- Move the description of the driver design from DT document to one
under Documentation/arm/keystone/knav-qmss.txt. Update the this
document with location of acc firmware available under
linux-firmware.git.

- Additionally added accumulator queue support optional so that lack
of firmware in the file system will not cause other queue types not
available due to driver probe failure.
