[PATCH 10/13] mpt3sas: Use Component img header to get Package ver

[Sreekanth Reddy <sreekanth.reddy@xxxxxxxxxxxx>]

The firmware image layout has been changed for
Aero controllers. All compatible HBA's has to get
Firmware Package version from Component Image
Header layout.

The Signature field in FW header is set to
0xEB000042 for products compatible with Component
Image Header.

For compatible Controllers, Driver fetches firmware
package version from ApplicationSpecific field of
Component Image Header.
