In the ACPI specification the PM1 register locations are well
defined, but the sleep type values are hardware specific. That
said, the Intel chipsets have been consistent with the values
they use. Therefore, provide those hardware definitions as well
a helper function for translating the hardware values to the
more high level ACPI sleep values.

The mainboard_smi_sleep() function takes ACPI sleep values
of the form S3=3, S4=4, S5=5, etc. All the chipsets ensure
that whatever hardware PM1 control register values are used
the interface to the mainboard is the same. Move all the
SMI handlers in the mainboard directory to not open code
the literal values 3 and 5 for ACPI_S3 and ACPI_S5.
There were a few notable exceptions where the code was
attempting to use the hardware values and not the common
translated values. The few users of SLEEP_STATE_X were
updated to align with ACPI_SX as those defines are
already equal. The removal of SLEEP_STATE_X defines is
forthcoming in a subsequent patch.

rollback counters from being deleted.
As implemented in a TPM1 compatible way, the PCR extension command
requires a prebuilt digest to calculate a new PCR value.
TPM2 specification introduces a PCR_Event command, where the TPM
itself calculates the digest of an arbitrary length string, and then
uses the calculated digest for PCR extension. PCR_Event could be a

The TPM2 specification allows defining NV ram spaces in a manner
that makes it impossible to remove the space until a certain PCR is in
a certain state.
This comes in handy when defining spaces for rollback counters: make
their removal depend on PCR0 being in the default state. Then extend
PCR0 to any value. This guarantees that the spaces can not be deleted.
Also, there is no need t create firmware and kernel rollback spaces
with different privileges: they both can be created with the same set of
properties, the firmware space could be locked by the RO firmware, and
the kernel space could be locked by the RW firmware thus providing
necessary privilege levels.

For coreboot TPM2 the use case session header is always the minimal
possible size, the only difference is that some commands require one
and some require two handles.
Refactor common session header marshalling code into a separate
function. This will be useful when more commands marshalling code is
added.

The function is reusing some variables which confuses the reader as
the variable names do not match their second function.
This patch edits the code for readability without changing

The marshaling/unmarshaling code is using integer values to represent
room left in the buffer, to be able to communicate three conditions:
positive number means there is room left in the buffer, zero means
that the exact amount of data in the buffer was unmarshaled and
negative value means that the result of the operation did not fit into
the buffer.
The implementation is wrong though, as it compares directly signed and
unsigned values, which is illegal, as signed values get promoted to
unsigned by the compiler.
This patch changes the marshaling code to use size_t for the size, and
use zero as marshaling failure indication - after all the buffer where
the data is marshaled to should definitely be large enough, and it is
reasonable to expect at least some room left in it after marshaling.
The unmarshaling situation is different: we sure want to communicate
errors to the caller, but do not want to propagate error return values
through multiple layers. This patch keeps the size value in int, but
checks if it is negative separately, before comparing with positive
values.
