Add support for MADT table flags. Currently the ACPI spec only defines the PCAT_COMPAT flag.

Summary of the PR

Table 5.20 of the ACPI spec. defines the flags that can be set for the MADT table, but currently it's not possible to set them. This PR adds support for defining MADT table flags (currently only PCAT_COMPAT exists).

Requirements

Before submitting your PR, please make sure you addressed the following

  • All added/changed public-facing functionality has entries in the "Upcoming
    Release" section of CHANGELOG.md (if no such section exists, please create one).
  • Any newly added unsafe code is properly documented.

Note: I'm not sure where to find the CHANGELOG.md file.
