mmc: sdhci-of-dwcmshc: Add command queue support for rockchip SOCs

This adds CQE support for the Rockchip RK3588 and RK3576 platform. To
be functional, the eMMC device-tree node must have a 'supports-cqe;'
flag property.

As the RK3576 device-tree has been upstreamed with the 'supports-cqe;'
property set by default, the kernel already tried to use CQE, which
results in system hang during suspend. This fixes the issue.
