Some hardware has an issue where the reset flags are lost on power cycle
because the EC backup ram loses power. This causes the flag to not power
on the AP (ap-off) to be lost.
In order to pass FAFT it is required that boards support this flag, so
this commit adds a workaround where the skylake chipset code will call into
the board to ask if it has working reset flags and if not it will skip the
PMIC reset if the "ap-off" flag has been set.
The "ap-off" flag is purely for testing, it is not possible for users to
do this without having access to the EC console. (which is currently not
possible at all with CCD unless you can also build a debug cr50 image)

Fizz has two power sources: barrel jack and type-c port. It
selects a power source at boot and does not dynamicall switch
to the other ports after that.
Fizz initializes all power suppliers of all ports to zero then
initialize the source supplier (barrel jack or type-c port).
When both sources are provided, it prefers a barrel jack. This
detection is done by reading the voltage on PPVAR_PWR_IN.
If barrel jack is detected as a sink, type-c port works as a
source only. If type-c port is detected as a sink, type-c
port works as a sink only.

In case there is a sudden power loss to PCH, then there are no eSPI VW
messages sent from the PCH to EC indicating power state transition into
S5. Instead, the eSPI compatibility spec defines such events as global
reset events. For global reset events, eSPI_Reset# signal is asserted
without SLP_SUS# being asserted. This acts as an indication to the EC
that there was a global reset event.
Add a callback chipset_handle_espi_reset_assert that takes any necessary

Prior x86 boards have had GPIO for toggling RCIN directly on the PCH,
although many likely had HW-assisted methods as well.
With eve we need to generate an eSPI Virtual Wire for RCIN, but in reality
software control over RCIN Virtual Wire is not available with the npcx EC,
so the legacy LPC interface for pulsing KBRST must be used instead as this
is the only way to generate RCIN.
This method will likely vary on different EC chips, but for skylake it
can just be abstracted into the LPC module.
