031366ea65 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)

fa590c222f staging: rts5208: add support for rts5208 and rts5288
There are still many rts5208/5288 card readers being used, but no
drivers are supported them in kernel now. This driver can make a
great convenience for people who use them.

Many other rts-series card reader are supported by mfd driver, but due
to much difference with others, rts5208/5288 can not add into mfd driver
pretty now, so we provide a separated driver here to support the device.
