[PATCH] ssb: drop use of non-existing CONFIG_SSB_DEBUG symbol

[Randy Dunlap]

CONFIG_SSB_DEBUG is used in one header file and nowhere else, so
remove it and the now-empty inline function that contained it. Also
remove the call to the empty inline function. The empty "default:"
case is kept to prevent 2 compiler warnings:

  drivers/ssb/main.c:1133:9: warning: enumeration value 'SSB_BUSTYPE_PCMCIA' not handled in switch [-Wswitch]
  drivers/ssb/main.c:1133:9: warning: enumeration value 'SSB_BUSTYPE_SDIO' not handled in switch [-Wswitch]
