Created IpmiTransport2 PPI/Protocol to support multiple
IPMI BMC Interface support such as KCS/BT/SSIF/IPMB with 2 API's
IpmiSubmitCommand2 & IpmiSubmitCommand2Ex.
IpmiSubmitCommand2 - This API use the default interface
(PcdDefaultSystemInterface) to send IPMI command.
IpmiSubmitCommand2Ex - This API use the specific interface type
to send IPMI command which is passed as an argument.
