Subject[PATCH V2] soc: imx: imx8m-blk-ctrl: Fix IMX8MN_DISPBLK_PD_ISI hang
The imx8mn clock list for the ISI lists four clocks, but DOMAIN_MAX_CLKS
was set to 3. Because of this, attempts to enable the fourth clock failed,
threw some splat, and ultimately hung.

Fixes: 7f511d514e8c ("soc: imx: imx8m-blk-ctrl: add i.MX8MN DISP blk-ctrl")
