At present interrupt routing is set up from arch_misc_init(). We can do it
a little later instead, in interrupt_init().
This removes the manual pirq_init() call. Where the platform does not have
an interrupt router defined in its device tree, no error is generated. Some
platforms do not have this.
This series adds an interrupt driver for x86. Since different platforms
can implement this in their own way, we no-longer need the platform-specific
weak function. We can also dispense with the arch_misc_init() call in some
cases.
