These two C2H events were defined as: 

// CLASS 1 - FW_OFLD
#define FWCMD_C2H_FUNC_BEACON_RESEND 0x3

// CLASS 0 - FW_INFO
#define FWCMD_C2H_FUNC_BCN_UPD_DONE 0x06

The implementation of handlers in vendor driver looks like does nothing
needed to be rewritten. Just add a dummy to represent that we have reviewed
the C2H events.
