platform/x86: intel-hid: simplify enabling/disabling HID events

Browse Source 
ACPI method HDSM takes a single integer argument.  Use
acpi_execute_simple_method() instead of acpi_evaluate_object() for
calling that ACPI method to simplify code and reduce the number of local
variables inside intel_hid_set_enable().
