staging: rtl8723bs: rework debug configuration handling

I ran into this warning during randconfig testing:

drivers/staging/rtl8723bs/os_dep/rtw_proc.c: In function 'rtw_adapter_proc_deinit':
drivers/staging/rtl8723bs/os_dep/rtw_proc.c:738:25: error: unused variable 'drv_proc' [-Werror=unused-variable]
drivers/staging/rtl8723bs/os_dep/rtw_proc.c: In function 'rtw_adapter_proc_replace':
drivers/staging/rtl8723bs/os_dep/rtw_proc.c:762:25: error: unused variable 'drv_proc' [-Werror=unused-variable]

The problem is that the code procfs code gets built even when CONFIG_PROC_FS
is disabled, but some functions are turned into empty stubs then. This
is easily addressed by adding an #ifdef around the definition of the
CONFIG_PROC_DEBUG macro.

However, I could not bear looking at the macro name that clashes with the
Kconfig name space, so I also renamed it to simply PROC_DEBUG, along with
the other rtl8723bs specific CONFIG_DEBUG_* macros that I renamed the same
way. This is consistent with how we handle the same checks in the non-staging
rtlwifi driver.

As the code path for !CONFIG_PROC_DEBUG had not been tested properly, it
turned out to be incorrect and requires adding 'static inline' annotations
for the stub handlers, and moving some variables around.

staging: Add rtl8723bs sdio wifi driver

The rtl8723bs is found on quite a few systems used by Linux users,
such as on Atom systems (Intel Computestick and various other
Atom based devices) and on many (budget) ARM boards such as
the CHIP.

The plan moving forward with this is for the new clean,
written from scratch, rtl8xxxu driver to eventually gain
support for sdio devices. But there is no clear timeline
for that, so lets add this driver included in staging for now.
