ACPI: support v5 (reduced HW) sleep interface
Note that this also fixes a broken input check in acpi_enter_sleep()
(previously validating the sleep->pm1[ab]_cnt_val relationship based
on acpi_sinfo.pm1b_cnt_val, which however gets set only subsequently).
Also adjust a few minor issues with the pre-v5 handling in
acpi_fadt_parse_sleep_info().
