[PATCH 3/4] phy: rockchip: phy-rockchip-inno-csidphy: add support for rk3576 variant

[Amin Gattout]

The two RK3576 MIPI CSI-2 DPHYs can be supported using the existing
phy-rockchip-inno-csidphy driver, the notable difference with the
RK3588 variant being that each PHY instance only has an APB reset
line.
