staging: rts5208: Remove TRACE_RET and TRACE_GOTO macros

Remove these flow hiding macros.

Miscellanea:

o Add a macro and function to replace a large inline
o Simplify #includes
o Add trace.c and update Makefile
o Remove static inline filename function and use kbasename instead

This reduces object size quite a lot: ~350KB (x86-64 allyesconfig)

Done via coccinelle script and some typing.
