mb/google/guybrush: Enable SOC_AMD_COMMON_BLOCK_I2C3_TPM_SHARED_WITH_PSP
Guybrush platforms have I2C3 controller which is shared between PSP and
X86. In order to enable cooperation, PSP acts as an arbitrator. Enable
SOC_AMD_COMMON_BLOCK_I2C3_TPM_SHARED_WITH_PSP, so that proper driver is
binded on the OS side.
With this change in place it is important to use correct kernel version
which has I2C-amdpsp driver [1] enabled. Otherwise, we won't have I2C3
available and thus TPM device available in OS, what may end up as a
serious error - guybrush refuses to boot without access to TPM.
BUG=b:204508404
BRANCH=guybrush
TEST=Build proper kernel and firmware. Run on guybrush and verify TPM
functionality.
