Subject: [PATCH] SUSE: Add the "t" hotkey

While graphical output is fancy and nice, in some environments (EFI) we can
only have fancy graphical on frame buffer _or_ ugly serial on any output.

To give the user a nicely graphical screen in the default case, but still
allow them to get their boot menu on the serial console, let's add a new
hidden option "t" that switches the output device back to the firmware default.

Signed-off-by: Alexander Graf <agraf@suse.de>
---

v1 -> v2

- use hiddenentry instead of --hidden

v2 -> v3 (by fvogt@suse.de)

- make it a runtime decision (bsc#1164385)
