ACPI: processor: idle: Rework first-level _LPI states processing

Browse source

The first-level _LPI states need not be combined with the previous
level and the entry method for them cannot be ACPI_CSTATE_INTEGER, so
process them directly in acpi_processor_get_lpi_info() instead of doing
a special case for them in flatten_lpi_states().

Also bail out if there are no _LPI states at the first level because
that means that there are no _LPI states at all.
