ACPI: Split out control for /proc/acpi entries from battery, ac, and sbs.

Introduce new ACPI_PROCFS_POWER (default Yes) config option and move
procfs code in battery, ac, and sbs drivers under it.
This is done to allow ACPI_PROCFS to be default No.

For backwards compatibility, this option allows
deprecated power /proc/acpi/ folders to exist, even when
they have been replaced by functions in /sys.
The deprecated folders (and their replacements) include:
/proc/acpi/battery/* (/sys/class/power_supply/*)
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
