'Console' is more readily understandable and technically more correct
than 'tty' for referring to the interfaces that Petitboot starts a UI on.

We need an absolute path to the serial@N device. It looks like some
kernels aren't reading the current path correctly, leading to no console
output.

If the boot_tty environment variable is set, determine which device path
to set in the linux,stdout-path property, which will instruct the next
kernel to use it as the primary console.

On OpenPOWER machines, kernels missing the AST video driver can use the
existing 'Open Firmware' framebuffer device code to inherit an existing
framebuffer from Petitboot. This requires us to translate the 64-bit
address of the framebuffer 'back' into a PCI address and write it into
an assigned-addresses property in the device tree.
