[thunderx] Use ThunderxConfigProtocol to obtain board configuration

Following changes were introduced:
 - added GetBgxProp and GetLmacProp methods to ThunderxConfigProtocol
 - replaced direct BOARD_CFG access with usage of introduced methods
 - removed redundant BOARD_CFG
 - changed GUID of ThunderxConfigProtocol, as this is not compatible
   with previous version
 - changed UINTN* to UINT64* buffer type to fix issue on 32-bit
   platforms with MAC address

This change allows us to avoid alignment of BOARD_CFG definitions
every time it changes in UEFI.
