fsi: sbefifo: Use specified value of start of response timeout
For some of the chip-ops where sbe needs to collect trace information,
sbe can take a long time (>30s) to respond. Currently these chip-ops
will timeout as the start of response timeout defaults to 10s.
Instead of default value, use specified value. The require timeout
value will be set using ioctl.
