The do_smm struct element in the mp_state struct was an int even though
it only had two possible states, so change it to bool to make this more
obvious. Also change the return type of is_smm_enabled from int to bool.

This sort-of reverts commit 075df92298fe3bb0ef04233395effe668c4a5550 and
fixes the underlying issue. The printf format string type/length
specifier for a size_t type is z.

Size_t seems to have a compiler dependency. When building on the
Purism librem 15v4, size_t is 'unsigned long'. In this instance,
the compiler is the coreboot configured cross-compiler. In another
instance, size_t is defined as 'unsigned short'. To get around
the formatting conflict caused by this, The variable of type
size_t was cast as 'unsigned int' in the format.

Jenkins does not build `config.stm` because the file name lacks the
mainboard name. So, the code was not being build-tested, and it does not
build because several files lacked the definition for `bool`.
Add the missing #include directives. Renaming the config file so that
Jenkins build-tests it is done in a follow-up.

This update is a combination of all four of the patches so that the
commit can be done without breaking parts of coreboot. This possible
breakage is because of the cross-dependencies between the original
separate patches would cause failure because of data structure changes.
security/intel/stm
This directory contains the functions that check and move the STM to the
MSEG, create its page tables, and create the BIOS resource list.
The STM page tables is a six page region located in the MSEG and are
pointed to by the CR3 Offset field in the MSEG header. The initial
page tables will identity map all memory between 0-4G. The STM starts
in IA32e mode, which requires page tables to exist at startup.
The BIOS resource list defines the resources that the SMI Handler is
allowed to access. This includes the SMM memory area where the SMI
handler resides and other resources such as I/O devices. The STM uses
the BIOS resource list to restrict the SMI handler's accesses.
The BIOS resource list is currently located in the same area as the
SMI handler. This location is shown in the comment section before
smm_load_module in smm_module_loader.c
Note: The files within security/intel/stm come directly from their
Tianocore counterparts. Unnecessary code has been removed and the
remaining code has been converted to meet coreboot coding requirements.
