[PATCH] staging: rtl8723bs: remove unused defines in HalBtcOutSrc.h

[Wang Yibo <szwyb123@gmail.com>]

HalBtcOutSrc.h still defines a number of constants that no code in the
driver ever references.  They either describe hardware variants the
RTL8723BS does not support - extra RF paths, dual-MAC/dual-PHY chips,
MIMO power save modes, coupler antennas - or were simply never wired up:

  BTC_RF_OFF, BTC_RF_ON, BTC_RF_B, BTC_RF_C, BTC_RF_D
  BTC_DMDP, BTC_DMSP, BTC_MP_UNKNOWN
  BTC_MIMO_PS_STATIC, BTC_MIMO_PS_DYNAMIC
  BTC_RATE_DISABLE, BTC_RATE_ENABLE
  BTC_ANT_WIFI_AT_CPL_MAIN, BTC_ANT_WIFI_AT_CPL_AUX
  WIFI_HS_CONNECTED, BTC_RSSI_LOW

Only BTC_RF_A is actually used, as the RF path argument of
fBtcSetRfReg().  The "coupler Antenna definition" comment is removed
together with the two defines it documented.

No functional change intended.
