CB:35077 pulled TPM measurement code into the bootblock, with the catch
that we'll only cache PCR extensions and not actually write them to the
TPM until it gets initialized in a later stage. The goal of this was to
keep the heavy TPM driver code out of the size-constrained bootblock.
Unfortunately, a small mistake in the tspi_tpm_is_setup() function
prevents the compiler from eliminating references to the TPM driver
code in the bootblock on platforms with CONFIG_VBOOT and
CONFIG_SEPARATE_VERSTAGE. In those cases vboot_logic_executed() is known
at compile-time to be 0, but that still makes the final expression
`return 0 || tpm_is_setup;`. We know that tpm_is_setup can never be set
to 1 in the bootblock, but the compiler doesn't.
This patch rewrites the logic slightly to achieve the same effect in a
way that the compiler can follow (because we only really need to check
tpm_is_setup in the stage that actually runs the vboot code).

Allow Chrome OS to be enabled for this QEMU target. By default
this does not change anything unless it is selected in the build
configuration, but it makes it possible.
Native VGA init is not forced when Chrome OS is enabled because the
drm-bochs driver does not work with chrome (even the latest upstream
kernel driver with drm atomic support) but it does work with virtio.
The coreboot graphics init needs to match what is selected with qemu
(with -vga std or -vga virtio) which in turn will determine which
kernel driver is used.
A second FMAP is added with both RW-A and RW-B regions which is
required by chromeos.
Recovery mode can be entered by supplying a custom fw_cfg option

This enables the mainboard to use a TPM if it is selected in the
configuration. By default this does nothing, but it allows the
TPM to be enabled and used with the CONFIG_USER_TPM2 Kconfig option.
Using a TPM with QEMU requires either a physical TPM backend or
the swtpm package with a socket:
-chardev socket,id=swtpm,path=/tmp/swtpm/socket
-tpmdev emulator,id=tpm0,chardev=swtpm
-device tpm-tis,tpmdev=tpm0
