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)
