Jiaxun Yang abc25a18a6 irqchip/mips-gic: Use raw spinlock for gic_lock
[ Upstream commit 3d6a0e4197c04599d75d85a608c8bb16a630a38c ]

Since we may hold gic_lock in hardirq context, use raw spinlock
makes more sense given that it is for low-level interrupt handling
routine and the critical section is small.

Fixes BUG:

README

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.
