Add controller logs to kdump. Driver allocates DMA memory and communicates this address to FW. In the event of system crash, host driver notifies the firmware about the crash and firmware posts all the necessary logs in the pre-allocated host buffer for firmware debugging. Once firmware notifies the completion of the log uploading to the host memory and host continues with the OS crash dump saving. This is a "feature" driven capability and is backward compatible with existing controller FW. Rename some prefixes for OFA (Online-Firmware Activation ofa_*) buffers to host_memory_*. So, not a lot of actual functional changes to smartpqi_init.c, mainly determining the memory size allocation. Added a function to notify the controller to copy debug data into host memory before continuing kdump. Most of the functional changes are in smartpqi_sis.c where the actual handshaking is done.
