Bug description:
[Impact]
After S3, DVD-ROM on HP ZBook 17 G5 stops working.
[Fix]
In the past we use dmi_match to set acpi_gbl_parse_table_as_term_list,
so the ACPI core can parse an entire ACPI table as a method.
Unfotunately this workaround doesn't work for the system in question.
So fully backport commit 5a8361f7ecce ("ACPICA: Integrate package
handling with module-level code") and subsequent fix commits, to solve
the issue.
[Test]
After applying the fix, DVD-ROM keeps working after S3.
[Regression Potential]
Medium. I've test several systems and I don't see anything break.
But if we want to be safe, we can merge this into Bionic after we are
sure there's no regression on OEM-B.
