This patchset adds a host power device and added it into the g220a mahcine. The BMC have a important is to control the power of the host, usually it is nessary in a hardware platform.
The BMC(soc) usually had a output pin to control the power of the host, and a input pin to get the power status of the host. The host power device is a generic device to simulate the host power, accept the power control command from the BMC and report the power status. Test on the g220a machine, the host power control command can be simply work.
