xtensa/esp32s3: Add timing delay set interface for QSPI

[Kevin-Zhou11]

Summary

When esp32s3 read from slave device through qspi, the data input signal has timing delay compared to clock signal, the higher the SPI frequency, the more impact to SPI sampling data, cause to receive wrong data.
esp32s3 has SPI timing compensation for this Scenario, add interface qspi driver to set timing compensation for the delay.

Impact

No impact

Testing

Build with esp32s3-devkit, test with project board.

Hi @Kevin-Zhou11 , thanks for the submission!

I will test it on our internal CI. Please wait to merge it.

Internal CI testing passed successfully. Where are these interfaces are being used?

@tmedicci, thanks for your review.

Our project has timing delayed issue, I call this interface in slave driver (such lan9250) after qspi initialize, below is an example.

  g_dev = esp32s3_qspibus_initialize(port);
  if (!g_dev)
    {
      nerr("ERROR: Failed to initialize QSPI port %d\n", port);
      return -ENODEV;
    }

  ret = esp32s3_qspibus_set_delay(g_dev, 1, 0, 0);
  if (ret < 0)
    {
      nerr("ERROR: Failed to set delay timing, ret=%d\n", ret);
    }

@acassis, thanks for your review.

I have fixed the alignment issue, please check.
