This patch fixes the checkpatch.pl warning "braces {} are not necessary"
in the rts5208 driver. Mostly applies to single-line return/goto if
blocks.

The driver has rather excessive amount of tracing code, which would be
better done using ftrace. This is obviously not a main feature of the
driver, and it should work just as well without it.
Removing it saves over 1300 lines of code and likely makes the driver
a bit faster by avoiding lots of calls into the timekeeping code.
I came across this while cleaning up the last users of the deprecated
getnstimeofday64() function, of which there is one in the now-removed
get_current_time() function of the rtsx driver that was only used for
tracing.

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)

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.
