mb/google/dedede: Add a board specific reset
When CSE Lite jumps from RO to RW, global reset is initiated. When AP is reset as part of global reset, TPM initialization fails. This is because AP reset is not detected by TPM hosting an older firmware version. Request Embedded Controller (EC) to perform AP reset so that TPM can detect that event. BUG=b:162290856, b:162386991 TEST=Ensure that the device boots to OS with the board-specific reset sequence when CSE Lite jumps from RO to RW with an older and newer Cr50 firmware.
