soc/amd/picasso,stoneyridge/acpi: use defines for MADT parameters
Using existing defines instead of magic values improves readability of the code. Also add comments to the MADT IRQ overrides to make it clearer what those actually do. TEST=Timeless build results in identical binary for amd/gardenia (Stoneyridge), amd/mandolin (Picasso) and amd/majolica (Cezanne) Signed-off-by: Felix Held <felix-coreboot@felixheld.de> Change-Id: I224ffbe8eb65bcdd5fc70c0ff8b15d55b3f6be01 Reviewed-on: https://review.coreboot.org/c/coreboot/+/55613 Reviewed-by: Marshall Dawson <marshalldawson3rd@gmail.com> Reviewed-by: Raul Rangel <rrangel@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
