There are four requirements for the SMI to hit a printk()
this commit now removes.
Build must have DEBUG_SMI=y, otherwise any printk() is a no-op
inside SMM.
ASL must have a TRAP() with argument 0x99 or 0x32 for SMIF value.
Platform needs to have IO Trap #3 enabled at IO 0x800.
The SMI monitor must call io_trap_handler for IO Trap #3.
At the moment, only getac/p470 would meet the above criteria
with TRAP(0x32) in its DSDT _INI method. The ASL ignores any
return value of TRAP() calls made.
A mainboard IO trap handler should have precedence over
a southbridge IO trap handler. At the moment we seem to have
no cases of the latter to support, so remove the latter.

C5, C6 and slfm depend on the southbridge and the northbridge to be able
to provide this functionality, with some just lacking the possibility to
do so. Move the devicetree configuration to the southbridge.
This removes the need for a magic lapic in the devicetree.

Later soc/intel/common/smbus addresses TCO2_STS as a separate
16-bit register, while baytrail and braswell assumes 32-bit
wide TCO1_STS to extend as TCO2_STS.
In src/soc/intel/denverton_ns:
#define TCO2_STS_SECOND_TO 0x02
In soc/intel/baytrail,braswell:
#define SECOND_TO_STS (1 << 17)
Elsewehere
#define SECOND_TO_STS (1 << 1)
It's expected that we remove the first (1 << 17) case and only
access TCO2_STS as a separate 16-bit register. For now, use
unique names to avoid confusion.

Tree is inconsistent with the use of TCO register space offsets and
related preprocessor defines. The legacy space was offset from ACPI
PM base by 0x60, but this changed with later platforms. The convenient
way is to define the TCO registers relative to its base address and
subtract 0x60 here, but this change cannot be easily done tree-wide or
in one go.
For the transient period, apply TCO_SPACE_NOT_YET_SPLIT flag until
all platforms use a clean style of tco_{read,write} accessor functions
instead of {read,write}_pmbase16(), or worse, inw/outl().

When ACPI GPE0 block was extended to 64 events or 8 bytes,
ACPI PM register space was slightly modified. After
adjustment, PM2_CNT register moved to 0x50 where register
SS_CNT was previously defined to be.
For platforms that have a valid use for PM2_CNT==0x50 in
their FADT, remove overlapping definition of SS_CNT.
On i82801dx/gx ACPI GPE0 supports 32 events, reset_gpe0_status()
incorrectly addressed also GPE0_EN register. For a bit cleaner
implementation, define GPE0_HAS_64_EVENTS.
