Starting from here CONFIG_TPM1 and CONFIG_TPM2 are no longer mutually
exclusive.

Convert TPM functions to return TPM error codes(referred to as
tpm_result_t) values to match the TCG standard.

Mainboards accessing the cr50 over an I2C bus may want to reuse some of
the same firmware version and BOARD_CFG logic, therefore refactor this
logic out into a bus-agnostic file, drivers/tpm/cr50.c. This file uses
the new tis_vendor_read/write() functions in order to access the cr50
regardless of the bus which is physically used. In order to leave SPI
devices intact, the tis_vendor_* functions are added to the SPI driver.
BUG=b:202246591
TEST=boot to OS on google/dratini, see the same FW version and board_cfg
console prints as before the change.

Introduce a helper to get the cached cr50 firmware version. This
information is in turn used to identify the strap configuration
supported by Cr50.
BUG=None
TEST=Ensure that Drawcia board boots to OS. Ensure that the version
cached cr50 firmware version is returned.

For Volteer (and future Tiger Lake boards) we can enable mode S0i3.4
only if we know that the Cr50 is generating 100us interrupt pulses.
We have to do so, because the SoC is not guaranteed to detect pulses
shorter than 100us in S0i3.4 substate.
A new Kconfig setting CR50_USE_LONG_INTERRUPT_PULSES controls new code
running in verstage, which will program a new Cr50 register, provided that
Cr50 firmware is new enough to support the register.

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.
BRANCH=none
BUG=chrome-os-partner:52132, chrome-os-partner:50645, chrome-os-partner:54141
TEST=with the rest of the patches applied coreboot is able complete
Chrome OS factory initialization of the TPM2 device.
