Subject: [PATCH v3 0/5] remoteproc: imx_rproc: misc clean up

This is the 3rd series to cleanup the driver.

Patch 1: simplify clock enable logic
Patch 2: Add a platform detach ops which will be easier to support new
         platforms
Patch 3: Enable runtime for all
Patch 4: Drop method assignment
Patch 5: Add an MAINTAINER entry for i.MX remoteproc drivers with
         Daniel/Shengjiu and me as maintainer

This is the last patchset to do the clean up for imx_rproc.c.
After imx_dsp_rproc.c moved to use platform ops with swith-case removed,
the method entry from dcfg could be removed in the end.

Tested V3 on
i.MX8MP-EVK, i.MX93-11x11-EVK.

Tested V1/V2 on
i.MX8MP-EVK, i.MX8MM-EVK, i.MX93-11x11-EVK, i.MX8QXP-MEK, and i.MX8ULP-EVK.

Thanks to Daniel and Frank for the internal reviewing.
