Currently coreboot has limited use for the SMM save state. Typically
the only thing needed is to get or set a few registers and to know
which CPU triggered the SMI (typically via an IO write). Abstracting
away different SMM save states would allow to put some SMM
functionality like the SMMSTORE entry in common places.
To save place platforms can select different SMM save sate ops that
should be implemented. For instance AMD platforms don't need Intel SMM
save state handling.
Some platforms can encounter CPUs with different save states, which
the code then handles at runtime by comparing the SMM save state
revision which is located at the same offset for all SMM save state
types.

In gpio.c file, we have community group array for each comm,
representing gpio groups within that community. Like there might be
group H,D, VGPIO and C within community 1. Community also may have
some reserved gpio and we also define those in an array which indicates
OS can't use those GPIO (through PAD_BASE_NONE)
Now when we define reserved pads in the middle of actual community
pads, it creates an issue while calculating an offset for GPIO
host own pad register. This is because function actually checks
current gpio index (lets say vgpio_39 in our case) and tries to get
group index from an array which we have defined. If we have defined
reserved gpios in between 2 communities, index calculated will also
account for reserved GPIO and register offset calculation will move
to next set of register (offset 0xC instead of offset 0x8).
Because of this coreboot won't configure HOST_OWN_PAD register correctly
and driver will not be able to get non-SMI interrupts for related gpio.
Align pad group as per EDS and pin-ctrl driver in linux kernel.

Some devices, such as cameras, can implement a physical switch to
disable the input on demand. Think of it like the typical privacy
sticker on the notebooks, but more elegant.
In order to notify the system about the status this feature, a GPIO is
typically used.
The map between a GPIO and the feature is done via ACPI, the same way as
the reset_gpio works.
This patch implements an extra field for the described privacy gpio.
This gpio does not require any extra handling from the power management.

Update Power Limit2 (PL2) minimum value to the same as maximum value
for magolor board. DTT does not throttle PL2, so this minimum value
change here does not impact any existing behavior on the system.
