ACPI: convert to sysfs framework
Setup new sysfs framework
1. Remove /sys/firmware/acpi
2. Add ACPI device in device tree.
File "eject" for every device that has _EJ0 method is moved from
/sys/firmware to /sys/devices.
Operation on this file is exactly the same as before.
i.e. echo 1 to "eject" will cause hot removal of this device.
Corresponding changes should be made in userspace for hot removal.
