Consolidate petitboot,tty and petitboot,console
Commit ce54f86 "Add petitboot,tty and track available consoles" added the petitboot,tty parameter, but the petitboot,console parameter is also recognised by Petitboot. These are ultimately handled by the 30-add-offb and 80-set-stdout hooks respectively, but exist for mostly the same purpose. We consolidate these down to just the original petitboot,console parameter. If the contents of petitboot,console have been configured by Petitboot (ie. it is of the form /dev/dev# [ Description ]) we behave as normal, otherwise we assume that petitboot,console contains a full OF path to the intended console device and do not allow it to be modified. This follows petitboot,console's original intent to be a debug aid, and takes precedence over any other use. The 80-set-stdout hook is removed as 30-add-offb now accounts for both use cases.
