ACPICA: Rename some function and variable names

Some function and variable names are renamed to be consistent with
ACPICA code base.

acpi_raw_enable_gpe -> acpi_ev_add_gpe_reference
acpi_raw_disable_gpe -> acpi_ev_remove_gpe_reference
acpi_gpe_can_wake -> acpi_setup_gpe_for_wake
acpi_gpe_wakeup -> acpi_set_gpe_wake_mask
acpi_update_gpes -> acpi_update_all_gpes
acpi_all_gpes_initialized -> acpi_gbl_all_gpes_initialized
acpi_handler_info -> acpi_gpe_handler_info
...
