Unlike the RK3588 variant, each PHY instance only has an APB reset line, so add the new compatible to the single-reset group as well. No fallback compatible is used because the RK3576 DPHYs match neither existing variant: their control bits sit in a dedicated CSI-DPHY GRF as on RK3588 (rather than in the shared VI GRF used on RK3568), while only a single APB reset is wired up, as on RK3568. Falling back to "rockchip,rk3588-csi-dphy" would make the driver request a second, non-existent reset, and falling back to "rockchip,rk3568-csi-dphy" would make it write to the wrong GRF offsets, so dedicated match data is required.
