soc/intel/common/cse_lite: Perform 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, in some boards TPM initialization fails. This is because AP reset is not detected by TPM hosting an older firmware version. To signal TPMs running older firmware version about AP reset, a modified reset sequence needs to be performed. Hence add support to perform board-specific reset sequence. 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.
