Modify plic_init() to skip .dts interrupt contexts other than supervisor external interrupt. The .dts entry for plic may specify multiple interrupt contexts. For example, it may assign two entries IRQ_M_EXT and IRQ_S_EXT, in that order, to the same interrupt controller. This patch modifies plic_init() to skip the IRQ_M_EXT context since IRQ_S_EXT is currently the only supported context. If IRQ_M_EXT is not skipped, plic_init() will report "handler already present for context" when it comes across the IRQ_S_EXT context in the next iteration of its loop. Without this patch, .dts would have to be edited to replace the value of IRQ_M_EXT with -1 for it to be skipped.

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.
