[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.
