Analyze and fix the following issue in the Linux kernel code: ACPICA: Ignore ACPI table signature for Load() operator
Problem Details: Only "SSDT" is acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. Therefore, signature validation is worthless.

Problem Details: Some quirks should be called with interrupt disabled, we can't directly call them in .resume_early.
