IPMI Channel commands implementation

IPMI Channel commands implemenation - squashed

commit e9a75d8dd6e89d17381f0310c7930586c6b79996
Author: AppaRao Puli <apparao.puli@intel.com>

    Channel layer separation

    De-coupling the channel management from ipmi channel commands
    implementation. This gives flexibility to load only needed
    stuff in different modules(host-ipmi or netipmid)

    IPMI Channel commands implementation

    Following IPMI channel commands are implemented.
     1) Set channel access (0x40)
     2) Get channel access (0x41)
     3) Get channel info (0x42)

    Also added code supported for LAN configuration parameters
     1) Authentication Type Support (selector #1)
     2) Authentication Type Enables (selector #2)
