MESA driver is creating protected context on every driver handle
creation to query caps bits for app. So when running CI tests,
they are observing hundreds of drm_errors when enabling PXP
in .config but using SOC fusing or BIOS configuration that cannot
support PXP sessions.

The fixes tag referenced below was to resolve a related issue
where we wanted to silence error messages, but that case was due
to outdated IFWI (firmware) that definitely needed an upgrade and
was, at that point, considered a one-off case as opposed to today's
realization that default CI was enabling PXP in kernel config for
all testing.

So with this patch, let's strike a balance between issues that is
critical but are root-caused from HW/platform gaps (louder drm-warn
but just ONCE) vs other cases where it could also come from session
state machine (which cannot be a WARN_ONCE since it can be triggered
due to runtime operation events).

Let's use helpers for these so as more functions are added in future
features / HW (or as FW designers continue to bless upstreaming of
the error codes and meanings), we only need to update the helpers.

NOTE: Don't completely remove FW errors (via drm_debug) or else cusomer
apps that really needs to know that content protection failed won't
be aware of it.

v2: - Add fixes tag (Trvtko)
v3: - Break multi-line drm_dbg strings into separate drm_dbg (Daniele)
    - Fix couple of typecasting nits (Daniele)
v4: - Unsuccessful PXP FW cmd due to platform configuration shouldn't
      use drm_WARN_once (Tvrtko), Switched to use drm_info_once.
v5: - Added "reported-and-tested" by Eero.

checkpatch seems to not like this tag. Maybe have 2 lines?

Reported-by: ...
Tested-by: ...

Can be fixed while merging.

It's not that. It's that checkpatch wants a link to the report
immediately following the Reported-by: or Reported-and-tested-by:.

If you have a link to the report, by all means add it, but it's no big
deal.
