C32 legacy code: change CONFIG_CPU_AMD_SOCKET_C32 to CONFIG_CPU_AMD_SOCKET_C32_NON_AGESA

Currently the C32 has some legacy boards which use the old C32 code. We need to seperate them.
CONFIG_CPU_AMD_SOCKET_C32 was used in legacy code before.
But it is not a good idea, so we change the code as follows:
So we use CONFIG_CPU_AMD_SOCKET_C32 to identify mainboard which uses agesa code,
and use  CONFIG_CPU_AMD_SOCKET_C32_NON_AGESA to identify mainboard which uses legacy code.
