[SCSI] bfa: fix chip and memory initialization 

Clear PSS memory reset that is set as part of power-on-reset (pci reset).
Complete PMM memory reset before BISTR start. Clear EDRAM BISTR start bit
after fixed delay. BISTR DONE bit status is not getting set. Use a fixed
1ms delay for BISTR now. Expose PMM IT memory definitions to host.
