There have been discussions about removing this since it does not seem
to be used much and only creates troubles for boards without defaults,
not to mention that it was configurable on many boards that do not
even feature uart.
It is still possible to configure the baudrate through the Kconfig
option.

Since commit 3bfd7cc (drivers/pc80: Rework normal / fallback selector
code) the reboot counter stored in `reboot_bits` isn't reset on a reboot
with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR
enabled, later stages (e.g. payload, OS) have to clear the counter too,
when they want to switch to normal boot. So change the bits to (h)ex
instead of (r)eserved.
To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also
remove all occurences of the obsolete `last_boot` bit that have sneaked
in again since 24391321 (mainboard: Remove last_boot NVRAM option).

Add a universal hybrid graphics driver compatible with
all supported lenovo devices.
Hybrid graphics allows to connect the display panel to
either of one GPUs.
As there are only two GPUs one GPIO needs to be toggled.
In case the discrete GPU is activated the panel is routed to it.
On deactivation the panel is routed to the integrated
GPU.
On lenovo laptops the dGPU is always connected to PEG10 and it is
save to disable the PEG slot on dGPU deactivation.
Use common gpio.c for southbridge I82801IX.
Tested on Lenovo T520 using Nvidia NVS 5200m.
Removed Lenovo T430s from the list of supported devices,
as the T430s only supports "muxless Optimus".
Depends on change id:
