There's a I2S bus on V3 that is not available on V3s. Add the V3-only peripheral's clocks and reset to the V3s CCU driver, bound to a new V3 compatible string. The driver name is not changed because it's part of the device tree binding (the header file name). Signed-off-by: Icenowy Zheng --- Changes in v4: - Add the missing MMC2 clock slices.
