[PATCH 5/9] drm: Use trace_call__##name() at guarded tracepoint call sites

[Steven Rostedt <rostedt@kernel.org>]

From: Vineeth Pillai <vineeth@bitbyteword.org>

Replace trace_foo() with the new trace_call__foo() at sites already
guarded by trace_foo_enabled(), avoiding a redundant
static_branch_unlikely() re-evaluation inside the tracepoint.
trace_call__foo() calls the tracepoint callbacks directly without
utilizing the static branch again.

Original v2 series:
https://lore.kernel.org/linux-trace-kernel/20260323160052.17528-1-vineeth@bitbyteword.org/

Parts of the original v2 series have already been merged in mainline.
This patch is being reposted as a follow-up cleanup for the remaining
unmerged pieces.
