* FADT also has a minor revision, which is stored in the FADT itself.

* TODO: Currently, we check for 6.5 as the minimum version to check
* for HW_REDUCED flag. However, once RISC-V updates are released in
* the ACPI spec, we need to update this check for exact minor revision

* tables such as RHCT (RISC-V Hart Capabilities Table) and RIMT
* (RISC-V I/O Mapping Table).
