Commit-Message
The dwcmshc used on Rockchip rk3568 and rk3588 can use cqe, so set the needed irq handler. Tested on a rk3588-tiger SoM with dd, hdparm and fio. fio performance does increase slightly from Run status group 0 (all jobs): READ: bw=209MiB/s (219MB/s), 209MiB/s-209MiB/s (219MB/s-219MB/s), io=4096MiB (4295MB), run=19607-19607msec without CQE to Run status group 0 (all jobs): READ: bw=215MiB/s (225MB/s), 215MiB/s-215MiB/s (225MB/s-225MB/s), io=4096MiB (4295MB), run=19062-19062msec with CQE enabled.
