sound fixes for 5.4-rc5

This is a usual small bump in the middle, we've got a set of ASoC
fixes in this week as shown in diffstat.

The only change in the core stuff is about (somewhat minor) PCM
debugfs error handling.  The major changes are rather for Intel
SOF and topology coverage, as well as other platform (rockchip,
samsung, stm) and codec fixes.

As non-ASoC changes, a couple of new HD-audio chip fixes and a
typo correction of USB-audio driver validation code are found.

Two fixes for komeda, one for typos and one to prevent an hardware issue
when flushing inactive pipes

UAPI Changes:

- Introduce a versioning of the i915-perf uapi (Lionel)
- Add support for perf configuration queries (Lionel)

  Allow listing perf configurations with IOCTL in addition
  to sysfs. This is useful in container usecases.

- Allow dynamic reconfiguration of the OA stream (Chris)

  Allows the OA stream to be reconfigured between
  batch buffers, giving greater flexibility in sampling.

- Allow holding preemption on filtered perf ctx

  Allow CAP_ADMIN to block pre-emption of a context
  to query performance counters without disturbances.

linux-kselftest-5.4-rc3

This Kselftest update for Linux 5.4-rc3 consists fixes for existing
tests and the framework. Cristian Marussi's patches add ability to
skip targets (tests) and exclude tests that didn't build from run-list.
These patches improve the Kselftest results. Ability to skip targets
helps avoid running tests that aren't supported in certain environments.
As an example, bpf tests from mainline aren't supported on stable kernels
and have dependency on bleeding edge llvm. Being able to skip bpf on
systems that can't meet this llvm dependency will be helpful.

Kselftest can be built and installed from the main Makefile. This change
help simplify Kselftest use-cases which addresses request from users.

Kees Cook added per test timeout support to limit individual test run-time.

UAPI Changes:
- Never allow userptr into the mappable GGTT (Chris)
  No existing users. Avoid anyone from even trying to
  spare a deadlock scenario.
