ACPICA: Use low-level GPE enable during GPE block initialization
The GPE block initialization code in acpi_ev_initialize_gpe_block()
uses acpi_set_gpe() to make sure that the GPEs with nonzero
runtime counter will remain enabled, but since it already has
a struct acpi_gpe_event_info object for each GPE, it might use
the low-level GPE enabling function, acpi_clear_and_enable_gpe(),
for this purpose.
To make that happen, move acpi_clear_and_enable_gpe() to
drivers/acpi/acpica/evgpe.c and rename it to acpi_ev_enable_gpe(),
modify the two existing users of it accordingly and modify
acpi_ev_initialize_gpe_block() to use it instead of acpi_set_gpe()
and to check its return value.
