[PATCH 4/5] ACPI: Remove CONFIG_ACPI_PROCFS_POWER and cm_sbsc.c

[tianyu.lan@intel.com]

From: Lan Tianyu <tianyu.lan@intel.com>

There is no user of cm_sbs.c and CONFIG_ACPI_PROCFS_POWER. So remove
them. Prepare for removing /proc/acpi

-          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-          they have been replaced by functions in /sys.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.
