mb/ocp/deltalake: Send OEM IPMI command for CMOS clear on RTC failure

When RTC failure is detected, send IPMI OEM command to issue CMOS clear.
This is to let the payload (LinuxBoot) handle the IPMI OEM CMOS
clear command by resetting RTC data, erasing RW_VPD (TODO) and add a
SEL, then reboot the system.

Tested=on OCP Delta Lake, after removing RTC battery we can see the above
flow can be executed correctly.
