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.

I wished there was a way to do this in smaller steps, but with
every line fixed an error somewhere else became visible. Here
is a (probably incomplete) list of the issues:
* Only one set of parentheses was supported. This is a hard
to solve problem without a real parser (one solution is to
use an recursive RE, see below).
* The precedence order was wrong. Might have been adapted just
to give a positive result for the arbitrary state of the tree.
* Numbered match variables (e.g. $1, $2, etc.) are not local.
Calling handle_expressions() recursively once with $1, then
with $2, resulted in using the final $2 after the first
recursive call (garbage, practically).
Also, symbol and expression parsing was mixed, making things
harder to follow.
To remedy the issues:
* Split handle_symbol() out. It is called with whitespace
stripped, to keep the uglier REs in handle_expressions().
* Match balanced parentheses and quotes when splitting
expressions. In this recursive RE
/(\((?:[^\(\)]++|(?-1))*\))/
the `(?-1)` references the outer-most group, thus the whole
expression itself. So it matches a pair of parentheses with
a mix of non-parentheses and the recursive rule itself inside.
This allows us to:
* Order the expression matches according to their precedence
rules. Now we can match `<expr> '||' <expr>` first as we should
and everything else falls into its place.
* Remove the bail-out that silenced the undefined behavior.
