Hm, dropping the legacy code at this point probably leads to a broken
state (bisectability...)
I would recommend to first move the boards to device tree and then drop
legacy stuff... Probably along these lines:
arm: vybrid: Enable lpuart support
arm: colibri-vf: Enable serial support
arm: vybrid: Drop enabling gpio, uart and spi in legacy mode
arm: vf610-twr: Add device tree files
arm: pcm052: Add device tree files
arm: vybrid: Update defconfig's
dm: lpuart: Drop the legacy code
dm: vybrid_gpio: Drop legacy code
