The SCI handler for the GPE associated with the Super I/O did not clear
the respective PME status bits resulting in the SCI reoccurring
endlessly. The /proc/interrupts reported millions of ACPI interrupts
generated in just a few minutes of uptime. The flood of interrupts
caused some units to be unusable in extreme cases once attempted to
boot Qubes OS for example. On systems like Qubes OS it had a huge
impact on performance due to many IPCs the SCIs caused under Xen.
Clear the PME bits of devices that report a PME event. Then clear
the global PME status bit at the end of SCI handler to prevent the SCI
from asserting again until a new event occurrs. With this change
the number of ACPI interrupts generated in the first minutes of uptime
settles at a few thousands.
TEST=Boot Qubes OS R4.1.2 on Dell OptiPlex 9010 SFF and check
/proc/interrupts in dom0 if the number of ACPI interrupts is only
a few thousands.

The fixed I/O resource descriptor macro implies that the device will
only decode 10 of the 16 IO port bits causing aliasing. Use an I/O port
descriptor instead and use Decode16 to tell the OS that this I/O
resource will decode all I/O address bits.

The SuperIO ACPI name was hard-coded to "SIO0". Allow setting the name
in the device tree so more than one SuperIO can be named.
An upcoming board (purism/librem_l1um_v2) has two SuperIOs - one in the
AST2500 BMC, and a Nuvoton NCT6791D used for hardware monitor, POST
display, etc.
Many boards have references to SIO0 already, so the default name is
still the same for a single SuperIO.

Simply return the current resource settings in the _PRS method. This
means that coreboot has to correctly set up the resources on the
device. This won't result in any regression as without _PRS the ACPI
OS would not know what resources settings are valid, so it would never
use _SRS.

PARALLEL_MP was working prior to board removal and no
relevant SMI handlers were implemented. So NO_SMM choice
is now selected.

The `_PRS` ACPI object is not needed for static (non-configurable)
devices. For devices where `_CRS` always provides the same set of
resource settings, drop the `_PRS` object. Note that every dropped
`_PRS` object only provides one set of resource settings, which is
identical to the resource settings provided by the `_CRS` object.
In addition, drop `IGNORE_IASL_MISSING_DEPENDENCY` from the two
mainboards using the MEC1308 code, `samsung/{lumpy, stumpy}`.

Now that the console system itself will clearly differentiate loglevels,
it is no longer necessary to explicitly add "ERROR: " in front of every
BIOS_ERR message to help it stand out more (and allow automated tooling
to grep for it). Removing all these extra .rodata characters should save
us a nice little amount of binary size.
This patch was created by running
find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';'
and doing some cursory review/cleanup on the result. Then doing the same
thing for BIOS_WARN with
's/printk\(\s*BIOS_WARNING,\s*"WARN(ING)?: /printk\(BIOS_WARNING, "/gi'
