clk: rockchip: rk3568: Add dummy I2S1_MCLKOUT_TX clock support

A RK3568 device tree pmic node can reference the I2S1_MCLKOUT_TX clock
in assigned-clocks, add dummy support to set parent of this clock to the
rk3568 cru driver.

Fixes probe of pmic driver and missing regulators on affected boards,
rk3568-evb and rk3568-rock-3a.
