The architecture name for our ARM port is armv7, not arm.
Hence, none of those flags were ever actually used.
Fix the architecture name and remove the flags, they should
not be set in xcompile, but in the Makefile, like in coreboot.

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.

Commit b8ad224 changed the memory address in lb_cbmem_ref coreboot
table entries from a pointer to a uint64_t. This change was introduced
to make the cbmem utility work on both 32bit and 64bit userland.
Unfortunately, this broke the cbmem utility running on older versions
of coreboot because they were still providing a 32bit only field for
the address while the cbmem utility would now take the following 4
bytes as upper 32bits of a pointer that can obviously not be
mmapped. This change checks if the size of the lb_cbmem_ref structure
provided by coreboot is smaller than expected, and if so, ignore the
upper 32bit of the address read.

The c-states are configured according to the BWG, however the
package c-states are disabled as they currently cause platform
instability. The exposed ACPI c-state to processor c-state mapping
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
registers as some of the MSRs are different and the proper values
are currently unknown. Lastly, some of the MSRs were renamed to
match the BWG.
Booted 3.8 kernel and used powertop to note package, core, and acpi
c-state residency.

This adds some macros for the common GPIO defines and drops
the gpio number definition from each entry. The end result
is much easier to read. The wtm2 mainboard gpio list is modified
to use this.
Also fix a bug in the LP version of get_gpio() that was always
returning zero due to a miscompare.

With the LynxPoint chipset there are more than 16
possible GPIOs that can trigger an SMI so we need
a mainboard handler that can support this.
There are only a handful of users of this function
so just change them all to use the new prototype.

Minor tweaks to variable names in the slippy mainboard
that make it easier to base a new board from without
as much renaming.
Also properly set up the thermal variables for the
thermal zone that is defined in ACPI instead of using
the generic setup from WTM2.
