Current logic only support main processor to stop/start the remote processor after crash. However to SoC, such as i.MX8QM/QXP, the remote processor could do attach recovery after crash and trigger watchdog to reboot itself. It does not need main processor to load image, or stop/start remote processor. Introduce two functions: rproc_attach_recovery, rproc_boot_recovery for the two cases. Boot recovery is as before, let main processor to help recovery, while attach recovery is to recover itself without help. To attach recovery, we only do detach and attach.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
