xucheng5 724ad008ab ctucanfd: increase rwcnt bitfield width and fix structure alignment 
The rwcnt (read word count) field in ctucanfd_frame_fmt_s was previously
limited to 4 bits, allowing a maximum value of 15. This is insufficient
to correctly represent the frame size (excluding the FRAME_FORMAT word)
for larger CAN FD frames as required by the CTU CAN FD hardware.

Increase the rwcnt bitfield width to support a larger range and adjust
the structure layout so that ctucanfd_frame_fmt_s has a size that is a
multiple of 4 bytes, as required by the hardware interface.

This change improves correctness and robustness when handling larger
CAN FD frames without affecting existing users.
