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.

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.

- Change the location of the PMA_CNT_BLOCK_ADDRESS to match
current documentation.
- cst_cnt should be 0 if smi_cmd == 0
- add a couple of default access sizes.
- Add a couple of #define values for unsupported C2 & C3 entries.
- Add PM Profile override value into amd/persimmon platform.
This does not use the #defines in acpi.h so that the files that
include this don't all need to start including acpi.h.

This change adds utility functions which allow to read any GPIO pin,
as well as a vector of GPIO pin values.
As presented, these functions will be available to Sandy Bridge and
Ivy Bridge systems only.
There is no error checking: trying to read GPIO pin number which
exceeds actual number of pins will return zero, trying to read GPIO
which is not actually configured as such will return unpredictable
value.
When reading a GPIO pin vector, the pin numbers are passed in an
array, terminated by -1. For instance, to read GPIO pins 4, 2, 15 as a
three bit number GPIO4 * 4 + GPIO2 * 2 + GPIO15 * 1, one should pass
pointer to array of {4, 2, 15, -1}.

Right now coreboot compilation fails when SPI flash debugging is
enabled. Fix it by using the right set of memory functions.
