staging: rtl8723bs: clean driver from unused RF paths

rtl8723bs support only two rf paths (A and B), remove all
the others (C, D, BC, ...) as they are unused. Keep
just one enum selecting rf path, remove unused macro
indicating max rf path number, add an item in rf_path
enum for this pourpose.

staging: rtl8723bs: remove commented out RT_TRACE logs in hal/ and os_dep/

Remove all commented out TR_TRACE calls.

Remove all of the RT_TRACE logs in hal/ and os_dep/ file as they
currently do nothing as they require the code to be modified by
hand in order to be turned on. This obviously has not happened
since the code was merged. Moreover it relies on an unneeded
private log level tracing which overrides the in-kernel public one,
so just remove them as they are unused.

staging: rtl8723bs: Remove phy_Config*With*ParaFile() calls

The rtl8723bs driver tries to load various parameters from disk,
circumventing the standard firmware loader mechanism and using DIY
code for this.

No devices which run the mainline kernel ship with these files and even
if these files were present then they still would not be loaded without
additional module parameters. To be precise the following 3 conditions
must all 3 be true for on disk parameters to be used:

1) The rtw_load_phy_file modparam must contain the mask for the type, this
defaults to(LOAD_BB_PG_PARA_FILE | LOAD_RF_TXPWR_LMT_PARA_FILE) so with
the default settings this condition is only true for:
phy_ConfigBBWithPgParaFile()
PHY_ConfigRFWithPowerLimitTableParaFile(); and
2) rtw_phy_file_path modparam must be set to say "/lib/firmware/"; and
3) Store a /lib/firmware/rtl8723b/XXX file in the expected format.

In practice all 3 being true never happens, so the
phy_Config*With*ParaFile() calls are nops, remove them.

The actual code implementing them will be removed in a separate patch.

Note the ODM_ConfigRFWithHeaderFile() and ODM_ConfigBBWithHeaderFile()
functions always return HAL_STATUS_SUCCESS, this patch makes use of this
to simplify the new code without the phy_Config*With*ParaFile() calls.

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.
