SRAM offset 0x0C04 is used by driver to inform the IPMI/ASF firmware

Browse Source 
about the various driver events like load, unload, reset, suspend,
restart, and ioctl operations.
Define driver's event rather than using hard-coded values.  We don't
still send suspend/resume event to firmware.

Previously bge(4) used BGE_SDI_STATUS to send events. Because driver
has to access firmware mail box to inform current state, using
BGE_SDI_STATUS register was wrong. The end result was the same as
BGE_SDI_STATUS is 0x0C04.

No functional changes.
