[PATCH v1 09/17] ACPI: processor: idle: Drop redundant _LPI presence checks

["Rafael J. Wysocki" <rafael@kernel.org>]

From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>

The acpi_has_method() checks for _LPI in acpi_processor_get_lpi_info()
are redundant because acpi_processor_evaluate_lpi() returns an error
when _LPI is not present, so drop them.

No intentional functional impact.
