Save the current exception frame pointer in the thread_info struct rather than
in a global variable as the latter makes SMP tricky, especially when preemption
is also enabled.
This also replaces __frame with current_frame() and rearranges header file
inclusions to make it all compile.

Implement the Panasonic MN10300 AM34 CPU subarch and implement SMP support for
MN10300. Also implement support for the MN2WS0060 processor and the ASB2364
evaluation board which are AM34 based.

MN10300 arch headers and place them instead in the same directories as contain
the .c files for the processor and unit implementations.
This permits the symlinks include/asm/proc and include/asm/unit to be
dispensed with. This does, however, require that #include <asm/proc/xxx.h> be
converted to #include <proc/xxx.h> and similarly for asm/unit -> unit.

Impact: fix build errors
Since the SPARSE IRQS changes redefined how the kstat irqs are
organized, arch's must use the new accessor function:
kstat_incr_irqs_this_cpu(irq, DESC);
If CONFIG_SPARSE_IRQS is set, then DESC is a pointer to the
irq_desc which has a pointer to the kstat_irqs. If not, then
the .irqs field of struct kernel_stat is used instead.

Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.
This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305. The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
