[PATCH 05/27] intel-rst: convert acpi_evaluate_object() to acpi_execute_simple_method()

[Zhang Rui <rui.zhang@xxxxxxxxx>]

acpi_execute_simple_method() is a new ACPI API introduced to invoke
an ACPI control method that has single integer parameter and no return value.

Convert acpi_evaluate_object() to acpi_execute_simple_method()
in drivers/platform/x86/intel-rst.c
