i3c: transfer pid from boardinfo to device info
I3C device PID could be defined in device tree and stored in
i3c_dev_boardinfo. It should be passed to i3c_device_info when
allocating a i3c_dev_desc.
Rational behind this change is: when users decide to use SETDASA to
assign a dynamic address with exactly the original static address, in
step of i3c_master_reattach_i3c_dev, this address is checked to be
taken. Then device information retrieving step is skipped. As a result,
though the i3c device is registered correctly, its device driver could
not be probed.
Tested: Tested with a I3C device. If assigned-address is set to be the
device's static address, without this change, its device driver could
not probed. And with this change, its driver is probed successfully.
