Subject: [PATCH 04/11] remoteproc: imx_dsp_rproc: Use dev_err_probe() for
 firmware and mode errors

Replace error logging and return handling in rproc_of_parse_firmware() and
imx_dsp_rproc_detect_mode() with dev_err_probe() to streamline error
reporting and improve consistency.

Reduces boilerplate and aligns with modern kernel error handling practices.
