soc/amd/picasso: use FADT devicetree configuration options
Two of the items in the FADT ACPI table frequently are partially board-
specific, so let's make it easy to update them via devicetree settings.
- fadt_boot_arch 0="legacy free" which while reasonable, probably isn't
what will be wanted by most mainboards, so this should generally get
updated in the specific devicetree.
- In fadt_flags all chipset-specific flags get set while the mainboard
has to set all other flags that it needs to have set.
This patch changes the default for fadt_boot_arch.
