Subject: [PATCH] thermal: intel: int340x_thermal: Remove unnecessary acpi_has_method() uses

acpi_evaluate_object() will already return in error if the method does not
exist. Checking if the method is absent before the acpi_evaluate_object()
call is not needed. Remove acpi_has_method() calls to avoid additional
work.
