Define BGE_FW_HB_TIMEOUT_SEC and remove one more magic value.

Browse Source 
bge(4) sends BGE_FW_CMD_DRV_ALIVE command to firmware every 2
seconds.  BGE_FW_CMD_DRV_ALIVE command requires 4 bytes data.  This
data contains timeout value in seconds until the next
BGE_FW_CMD_DRV_ALIVE command.
Broadcom recommends driver set the value 3 times longer than the
interval that it sends BGE_FW_CMD_DRV_ALIVE.  Currently bge(4) uses
3 seconds so probably we have to increase it in future and use
different ALIVE command(e.g. BGE_FW_CMD_DRV_ALIVE3).

No functional changes.
