In order to support the GSMI interface the SMI handler needs
to find and use the state save area from the same CPU that
initiated the SMI. In this case it is a synchronous SMI
resulting form an IO write to port 0xB2.
To find the right CPU state save area iterate over the region
until the "IO Misc Info" field reports the expected value and
then proceed to use that state save area.
This is needed because the coreboot SMI handler only executes on
one core, and that core is non-deterministic. It is likely that
the core executing the C SMM handler is not the same one that
actually did the IO write to 0xB2 and generated the SMI.
The GSMI parameter buffer is passed as a pointer to EBX in the
tate save area, and the GSMI command is extracted from EAX before
it is used as the return value.
This interface is tested by enabling CONFIG_GOOGLE_GSMI in the
kernel and generating events and verifying that they end up
in the event log.

This was introduced when porting the SPI driver over from u-boot but it
is not needed. Hence drop the extra typedef and use device_t instead.

CPUs with configurable TDP will run the TSC at the max non-turbo
ratio for the maximum TDP value, which can cause issues if another
TDP is desired. To deal with this we set the flex ratio to the
nominal TDP ratio early in the boot and then configure the Soft
Reset Data registers so the PCH can tell the CPU what frequency
to run at after a reset.
This is done very early in the bootblock because it is necessary
to reset the system after setting a flex ratio.
The end result is that the TSC will now increment at the max
non-turbo frequency for the nominal TDP.
On some system with 1.8GHz CPU ensure that the kernel
detects the CPU speed as ~1800mhz rather than ~2300mhz:
> dmesg | grep "MHz processor"
[ 0.004000] Detected 1795.801 MHz processor.

There are enough differences that it is worth defining the
proper map for the sandybridge/ivybridge CPUs. The state
save map was not being addressed properly for TSEG and
needs to use the right offset instead of pointing in ASEG.
To do this properly add a required southbridge export to
return the TSEG base and use that where appropriate.

- add Kconfig option for CONFIG_SPI_FLASH_SMM
- compile subsystem and chip drivers for smm if enabled
- change mdelay(1) to udelay(500) since mdelay is not defined
in SMM and a 1ms delay is worth avoiding
- make flash chip structure non-const so the probe function
pointers can be relocated for use in TSEG
- Make SMM PCI access possible in southbridge SPI code

In the short term there might be devices with Sandy Bridge CPUs
on mainboards with Panther Point PCHes. While this configuration
option is perfectly valid, coreboot currently ties Sandy Bridge to
Cougar Point and Ivy Bridge to Panther Point. One occurence is in
the ME handling code.
To make coreboot most flexible, compile both ME handlers into
coreboot and decide at runtime which one to use.
