The uPEP device is required to support S0i3. The device has been written
in ASL to make it easier to read and maintain. The device constraints
are purely informational. We use a dummy constraint like the Intel
platforms to keep both linux and Windows functional.
In order for this device to be used by the linux kernel the
ACPI_FADT_LOW_PWR_IDLE_S0 flag must be set. So including it
unconditionally doesn't cause any problems.
The AMD Modern Standby BIOS Implementation Guide defines two UUIDs,
one for getting the device constraints, and one for handling
notifications. This differs from the Intel specification and the linux
driver implementation. For this reason I haven't implemented any of the
notification callbacks yet.

CB:31250 ("soc/intel/cannonlake: Configure GPIOs again after FSP-S is
done") introduced a workaround in coreboot for `soc/intel/cannonlake`
platforms to save and restore GPIO configuration performed by
mainboard across call to FSP Silicon Init (FSP-S). This workaround was
required because FSP-S was configuring GPIOs differently than
mainboard resulting in boot and runtime issues because of
misconfigured GPIOs.
This issue has since been fixed in FSP (verified with FSP v1263 on
hatch). However, there were still 4 boards in coreboot using
`cnl_configure_pads()`. As part of RFC CB:50829, librem_cnl, clevo/cml-u
and system76/lemp9 were tested to ensure that this workaround is no
longer required.
This change drops the workaround using `cnl_configure_pads()` and
updates all mainboards to use `gpio_configure_pads()` instead.
