[SCSI] mpt fusion: Request I/O resources only when required
This patch modifies the I/O resource allocation behavior of FUSION driver. The current version of driver allocates the I/O resources even if they are not required and this creates trouble in low resource environments. This driver now uses pci_enable_device_mem/pci_enable_device functions to differentiate the resource allocations.
