This introduces a SPI TPM driver compliant with the TCG issued "TPM
Profile (PTP) Specification Revision 00.43" which can be found by
googling its title.
The driver implements both the hardware flow control protocol and the
TPM state machine.
The hardware flow control allows to map SPI based TPM devices to the
LPC address space on x86 platforms, on all other platforms it needs to
be implemented in the driver software.
The tis layer is somewhat superficial, it might have to be expanded
later.
A lot more implementation details can be found in the code comments.
Also, it is worth mentioning that this is not a complete version of
the driver: its robustness needs to be improved, delay loops need to
be bound, error conditions need to propagate up the call stack.

Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.
With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).
This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.
MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.
BRANCH=none

TEST=verified that none of the generated board configurations change
as a result of this patch. With the rest of the stack in place it
is possible to configure different combinations of TPM types and
interfaces for ARM and x86 boards.

Previous FSP implementations in coreboot have included FspUpdVpd.h
directly, along with with efi headers. Instead of taking that
approach in FSP 2.0, we provide a semantic patch that, with minimal
modifications, makes FspUpdVpd.h easier to include in coreboot, and
eliminates reliance on external headers and definitions.
