Add CPLD class for Mihawk platform
If PGOOD signal is abnormal when chassis power_on, read
Mihawk's CPLD-register via I2C to confirm the error.
First, confirm whether the power_on_error signal is 1
when chassis power_on(1 means abnormal).
If the signal is 1, read the error-code-register to
analysis reason.
Second, runtime to confirm whether the power_ready_error
signal is 1 after chassis power_on(1 means abnormal).
If the signal is 1, read the error-code-register to
analysis reason and shutdown the chassis.
Tested:
Use command "obmcutil chassiskill" to trigger PGOOD error
action analysis during chassis power on.
