df06bf91a5 alif/ospi_ext: Optimize XIP speed. 
This change increases XIP read speed to ~30Mbytes/s at 50MHz DDR:
- Enable continuous mode.
- Remove hard-coded settings.
- Set XIP continuous mode timeout.

The prefetch remains disabled.  Although enabling the prefetch gives the
best performance for the CPU in XIP mode, it must be disabled when the NPU
accesses the OSPI flash.
