This patchset adds i3c master support for the qualcomm's QUPV3 based 
Serial engine (SE) controller. 

The I3C SE(Serial Engine) controller implements I3C master functionality
as defined in the MIPI Specifications for I3C, Version 1.0. 

This patchset was tested on Kailua SM8550 MTP device and data transfer
has been tested in I3C SDR mode with i2c and i3c target devices.

Features tested and supported :
  Standard CCC commands.
  I3C SDR mode private transfers in PIO mode.
  I2C transfers in PIO mode.

Can you share with which I3C targets you tested this driver?

Tested with Prodigy : one target as i3c and another as i2c. It's not 
having on board slave, but internally  we have target devices connected.
