Rename struct i3c_priv_xfer to struct i3c_xfer, since private xfer in the I3C spec refers only to SDR transfers. Ref: i3c spec ver1.2, section 3, Technical Overview. i3c_xfer will be used for both SDR and HDR. Rename enum i3c_hdr_mode to i3c_xfer_mode. Previous definition need match CCC GET_CAP1 bit position. Use 31 as SDR transfer mode. Add i3c_device_do_xfers() with an xfer mode argument, while keeping i3c_device_do_priv_xfers() as a wrapper that calls i3c_device_do_xfers() with I3C_SDR for backward compatibility. Introduce a 'cmd' field in struct i3c_xfer as an anonymous union with 'rnw', since HDR mode uses read/write commands instead of the SDR address bit. Add .i3c_xfers() callback for master controllers. If not implemented, fall back to SDR with .priv_xfers(). The .priv_xfers() API can be removed once all controllers switch to .i3c_xfers(). Add 'mode_mask' bitmask to advertise controller capability.
