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

	bool "Deprecated power /proc/acpi directories"

	help

	  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          they have been replaced by functions in /sys.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.
