ACPI: Schedule /proc/acpi/event for removal



Schedule /proc/acpi/event for removal in 6 months.

Re-name acpi_bus_generate_event() to acpi_bus_generate_proc_event()
to make sure there is no confusion that it is for /proc/acpi/event only.

Add CONFIG_ACPI_PROC_EVENT to allow removal of /proc/acpi/event.
There is no functional change if CONFIG_ACPI_PROC_EVENT=y

---help---
A user-space daemon, acpi, typically read /proc/acpi/event
and handled all ACPI sub-system generated events.
These events are now delivered to user-space via
either the input layer, or as netlink events.
This build option enables the old code for for legacy
user-space implementation. After some time, this will
be moved under CONFIG_ACPI_PROCFS, and then deleted.
