power: Rename enable/disable autosleep to init/exit

The functions below has been renamed:
 - power_enable_autosleep() => power_init_autosleep()
 - power_disable_autosleep() => power_exit_autosleep()

Those functions are only executed once, after booting done and before
shutting down. Therefore the name init/exit is much proper than
enable/disable. In addition, for the power_init_autosleep(), it has
changed to acquire mainlock before writing "mem" on the
/sys/power/autosleep. This prevents system from going suspend just
after the writing "mem" on /sys/power/autosleep.
