Add support for GSPI controller in Intel PCH. This controller is
compliant with PXA2xx SPI controller with some additional registers to
provide more fine-grained control of the SPI bus. Currently, DMA is
not enabled as this driver might be used before memory is up (e.g. TPM
on SPI).
Also, provide common GSPI config structure that can be included by
SoCs in chip config to allow mainboards to configure GSPI
bus. Additionally, provide an option for SoCs to configure BAR for
GSPI controllers before memory is up.

In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.
There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.
This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).
Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

No board has ever tried to combine CONFIG_SEPARATE_VERSTAGE with
CONFIG_VBOOT_STARTS_IN_ROMSTAGE. There are probably many reasons why
this wouldn't work (e.g. x86 CAR migration logic currently always
assumes verstage code to run pre-migration). It would also not really
make sense: the reason we use separate verstages is to decrease
bootblock size (mitigating the boot speed cost of slow boot ROM SPI
drivers) and to allow the SRAM-saving RETURN_FROM_VERSTAGE trick,
neither of which would apply to the after-romstage case. It is better to
just forbid that case explicitly and give programmers more guarantees
about what the verstage is (e.g. now the assumption that it runs pre-RAM
is always valid).
Since Kconfig dependencies aren't always guaranteed in the face of
'select' statements, also add some explicit compile-time assertions to
the vboot code. We can simplify some of the loader logic which now no
longer needs to provide for the forbidden case. In addition, also try to
make some of the loader logic more readable by writing it in a more
functional style that allows us to put more assertions about which cases
should be unreachable in there, which will hopefully make it more robust
and fail-fast with future changes (e.g. addition of new stages).
