Pull spi fixes from Mark Brown: "A few small fixes for SPI, one core fix
  that only applies in cases where we're handling DT overlays and a
  couple of driver specific fixes:

   - Fix handling of error cases when instantiating DT overlays so we
     don't end up just ignoring devices that encountered an error during
     instantiation.

   - Avoid reading uninitialized data when handing spurious interrupts
     in the espi driver.

   - A driver specific fix for the dspi driver to fix a bad interaction
     with u-boot"
