meta-yosemitev2: add system get/set guid support

Added get/set system GUID command for multi host YosemiteV2,
it reads/writes guid to the corresponding hosts Bridge IC(BIC).

Tested:

Verified this with host reboot(BIOS automatically
sends get GUID command to BMC).

Verified this ipmitool.
 Get System GUID:
 ipmitool raw 60x37

 Set System GUID:
 ipmitool raw 0x30 0xEF 0 252 109 1 0 135 236 73 26
 54 249 84 1 1 80 7 8
