ACPI: delete CONFIG_ACPI_PROCFS_POWER and power procfs I/F in 2.6.39
sysfs I/F for ACPI power devices, including AC and Battery, has been working in upstream kenrel since 2.6.24, Sep 2007. In 2.6.37, we made the sysfs I/F always built in and this option disabled by default. Now, we plan to remove this option and the ACPI power procfs interface in 2.6.39. First, update the feature-removal-schedule to announce this change. Second, add runtime warnings in ACPI AC/Battery/SBS driver, so that users will notice this change even if "make oldconfig" is used.
