LynxPoint-LP has an additional 16 entries in the IOAPIC that
can be assigned to specific GPIOs when they are configured
as PIRQ.
The maximum redirection entries field in the IOAPIC needs to
be set to 0x27 when this is enabled.
Additionally specific GPIOs need to be routed to PIRQ so they
interrupt via the IOAPIC instead of the GPIO IRQ 14/15.

In order to report whether coreboot enabled a SerialIO device
in ACPI mode we had been relying on reading NVS in the _STA
method for the SerialIO device.
The ACPI _STA method has restrictions on what it can access
and is unable to access OperationRegions outside its scope
which means it should not be trying to read NVS.
This change adds a new SSDT to the ACPI tables and fills it
with constants that indicate whether or not a device is enabled
in ACPI mode.
The ACPI code is changed to read these variables from the
SSDT and use that instead of trying to query a variable in NVS.
Attempt to use lpt-clk driver to probe the
device clocks for SerialIO devices and see that the kernel
does not complain about accessing the GNVS region.

are as follows for ULT boards:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C7S long latency)
ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:
ACPI(C1) = MWAIT(C1E)
ACPI(C2) = MWAIT(C3)
ACPI(C3) = MWAIT(C7S)
Included in this patch is removing the updating of current limit
