ACPI: processor: idle: Ignore _LPI states with SYSTEMIO entry method

Browse source

The only entry method for _LPI states supported by acpi_idle_lpi_enter()
is FFH and it is better to ignore _LPI states with the SYSTEMIO entry
method upfront than return an error from acpi_idle_lpi_enter() on
attempts to use them.

Update acpi_processor_evaluate_lpi() accordingly.
