imx: imx8ulp: enable MU0_B clk by default
Enable MU0_B clk by default. When M33 image is loaded by Jlink,
the previous method not enable MU0_B clk and not able to communicate
with M33, so let's enable it by default.
And we not put it under kernel dts, because it conflicts with i.MX8QM
suspend/resume logic which requires large change.
