Shared interrupts with IRQ_NOAUTOEN got a warning added with commit
04c848d39879 ("genirq: Warn when IRQ_NOAUTOEN is used with shared
interrupts").
Let's just drop the IRQ_NOAUTOEN use for omap3 PRM shared interrupt as
it does not seem to cause any other issues based on my testing. We have
moved a lot of the code to initialize later, and whatever problems the
legacy booting had seem to be gone now with pinctrl driver and device
tree based booting.
Otherwise we will get:
WARNING: CPU: 0 PID: 1 at kernel/irq/manage.c:1348 __setup_irq+0x5d0/0x64c

Note that we also need to remove the related enable_irq() to avoid
getting the following:

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
