rtlwifi: btcoex: Add wifi_only series ops to control solo card

Originally, btcoex controls the antenna of combo card, but solo card
is also needed to setup properly. The new ops are named with suffix
'_wifi_only' opposited to original btc_ops, and new structures and
definitions are also introduced. The wifi_only oly contains four ops that
are initial variable, hw config, scan notify, and switch band notify.

rtlwifi: Improve debugging by using debugfs

Use debugfs to dump register and btcoex status, and also write registers
and h2c.

We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address
as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc.
An example is
/sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0

This change permits examination of device registers in a dynamic manner,
a feature not available with the current debug mechanism.

rtlwifi: Add BT_MP_INFO to c2h handler.

rtlwifi: rtl8723be: btcoexist: Add single_ant_path

Some devices with RTL8732BE wifi/Bluetooth adapters are shipped with only
a single antenna. On a subset of these, the EEPROM is incorectly coded
to indicate the wrong connection. The resulting problems have been fixed
for wifi. This change handles them for BT.

rtlwifi: rtl818x: Move drivers into new realtek directory

Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.
