clk: imx: clk-imx8mn: fix memory leak in imx8mn_clocks_probe
Use devm_of_iomap() instead of of_iomap() to automatically handle
the unused ioremap region.
If any error occurs, regions allocated by kzalloc() will leak,
but using devm_kzalloc() instead will automatically free the memory
using devm_kfree().
Fixes: daeb14545514 ("clk: imx: imx8mn: Switch to clk_hw based API")
Fixes: 96d6392b54db ("clk: imx: Add support for i.MX8MN clock driver")
