Added new configuration for TwinLake board.

Added a new configuration to define the properties for
Ipmbpower state of each host. Bus will represent the
IPMB channel in which Ipmbpower state information will
be read. which is based on IPMB sendRequest and display
the Ipmbpower state using busctl in dbus-sensors repo
for multi host.

Example :

root@yosemitev2:~# busctl tree xyz.openbmc_project.EntityManager
`-/xyz
  `-/xyz/openbmc_project
    |-/xyz/openbmc_project/EntityManager
    `-/xyz/openbmc_project/inventory
      `-/xyz/openbmc_project/inventory/system
        `-/xyz/openbmc_project/inventory/system/board
          |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_1
          | |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_1
/1_Twinlake
          |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_2
          | |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_2
/2_Twinlake
                           .............
                           .............
          |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_N
          | |-/xyz/openbmc_project/inventory/system/board/Twin_Lake_N
/N_Twinlake

TESTED : Tested on Facebook YosemiteV2 hardware.
Verified all the host Gpio PGood state.
