[PATCH v2 2/4] dt-bindings: phy: rockchip-inno-csi-dphy: add rk3576 variant

[Amin Gattout]

The Rockchip RK3576 features two MIPI CSI-2 DPHYs compatible with this
binding. 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.
