scsi: pm80xx: Fix driver fatal dump failure
The function pm80xx_get_fatal_dump() has two issues that result in the
fatal dump not being able to complete successfully.
1. Trying to collect fatal_logs from the application fails because we are
not shifting the MEMBASE-II register properly. Once we read 64K region
of data we have to shift the MEMBASE-II register and read the next
chunk. Only then would we be able to get complete data.
2. If a timeout occurs, our application will get stuck.
