kernel: add architecture interface headers

Browse source 
include/sys/arch_inlines.h will contain all architecture APIs
that are used by public inline functions and macros,
with implementations deriving from include/arch/cpu.h.

kernel/include/arch_interface.h will contain everything
else, with implementations deriving from
arch/*/include/kernel_arch_func.h.

Instances of duplicate documentation for these APIs have been
removed; implementation details have been left in place.

/**
* Configure a static interrupt.
*
* All arguments must be computable by the compiler at build time.
*
* Internally this function does a few things:
*
* 1. The enum statement has no effect but forces the compiler to only
* accept constant values for the irq_p parameter, very important as the
* numerical IRQ line is used to create a named section.
*
* 2. An instance of struct _isr_table_entry is created containing the ISR and
* its parameter. If you look at how _sw_isr_table is created, each entry in
* the array is in its own section named by the IRQ line number. What we are
* doing here is to override one of the default entries (which points to the
* spurious IRQ handler) with what was supplied here.
*
* There is no notion of priority with the Nios II internal interrupt
/* There is no notion of priority with the Nios II internal interrupt
