[PATCH 0/4] i3c: switch to use switch to use i3c_xfer from i3c_priv_xfer

[Frank Li]

This depend on the serise
https://lore.kernel.org/linux-i3c/20251028-i3c_ddr-v8-0-795ded2db8c2@nxp.com/T/#t

Convert all existed i3c consumer to new API.

The below patch need be applied after other patch applied to avoid build
break.

[PATCH 1/4] hwmon: (lm75): switch to use i3c_xfer from i3c_priv_xfer

[Frank Li]

Switch to use i3c_xfer instead of i3c_priv_xfer because framework will
update to support HDR mode. i3c_priv_xfer is now an alias of i3c_xfer.

Replace i3c_device_do_priv_xfers() with i3c_device_do_xfers(..., I3C_SDR)
to align with the new API.

Prepare for removal of i3c_priv_xfer and i3c_device_do_priv_xfers().
