	ACPI: Remove CONFIG_ACPI_PROCFS_POWER and cm_sbsc.c
There is no user of cm_sbs.c and CONFIG_ACPI_PROCFS_POWER. So remove them. Prepare for removing /proc/acpi Signed-off-by: Lan Tianyu <tianyu.lan@intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

	  For backwards compatibility, this option allows
 | 
					 | 
				
			||||||
          deprecated power /proc/acpi/ directories to exist, even when
 | 
					 | 
				
			||||||
          they have been replaced by functions in /sys.
 | 
					 | 
				
			||||||
          The deprecated directories (and their replacements) include:
 | 
					 | 
				
			||||||
	  /proc/acpi/battery/* (/sys/class/power_supply/*)
 | 
					 | 
				
			||||||
	  /proc/acpi/ac_adapter/* (sys/class/power_supply/*)
 | 
					 | 
				
			||||||
	  This option has no effect on /proc/acpi/ directories
 | 
					 | 
				
			||||||
	  and functions, which do not yet exist in /sys
 | 
					 | 
				
			||||||
	  This option, together with the proc directories, will be
 | 
					 | 
				
			||||||
	  deleted in 2.6.39.
