[PATCH 4/4] tracing/mmiotrace: Clean up coding style and redundant debug logs

["Masami Hiramatsu (Google)" <mhiramat@kernel.org>]

From: Masami Hiramatsu (Google) <mhiramat@kernel.org>

Clean up coding style issues in trace_mmiotrace.c:
- Remove redundant pr_debug() entries in tracer callbacks.
- Fix opening brace placement for mmio_tracer.
- Prefer 'unsigned int' to bare 'unsigned'.
- Add missing blank lines after local variable declarations.
