google/oak: Support cr50 over I2C on rowan
This patch enables TPM2 using cr50 over I2C for the Rowan board, and
adds an mt8173 specific TPM IRQ polling function. The function relies on
the appropriate EINT input configured to trigger the ready status on
the rising edge.
The cr50 TPM is on I2C address 0x50.
The cr50 interrupt GPIO is also made available for use by depthcharge
via the coreboot tables.
BRANCH=none
BUG=b:36786804
TEST=Boot rowan w/ serial enabled, verify coreboot and depthcharge are
configured to use IRQ flow control when talking to the Cr50 TPM.
