To enable RO CBFS verification in AMD platforms with PSP verstage,
metadata hash for RO CBFS is kept as part of verstage. This means any
updates to RO CBFS, before WP is enabled, requires updating the
metadata hash in the verstage. Hence keep the metadata hash outside the
signed range of PSP verstage. This means the metadata hash gets loaded
as part of loading PSP verstage while still being excluded from the
verification of PSP verstage.
This change keeps the metadata hash outside the PSP footer data. This

Move the Raydium touchscreen to the baseboard devicetree. Since only the
liara variant uses a level IRQ as I2C devices are supposed to, all other
board variants still override this to use an edge IRQ which were added
as a workaround to make the touchscreen work on the other devices. Right
now it's unclear to me if that edge IRQ workaround was only needed
temporarily and can now be removed, so I'll keep it as it was for now.
If this turns out to be no longer needed on the other variants, the
overrides can be dropped in the future.
