This patch removes the IRQF_DISABLED flag from mn10300 architecture
code. It's a NOOP since 2.6.35 and it will be removed one day.

Move the static inline function setup_jiffies_interrupt() from
<asm/timex.h> to arch/mn10300/kernel/cevt-mn10300.c, which is its only
callsite.
This allows to remove the inclusion of <asm/hardirq.h> and <linux/irq.h>
from <asm/timex.h> and <unit/timex.h>, fixing include hell like:
include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
include/linux/jiffies.h:46:42: error: division by zero in #if
...
make[4]: *** [arch/mn10300/kernel/asm-offsets.s] Error 1
and (after a quick hack for the above by defining CLOCK_TICK_RATE in
<linux/jiffies.h>):
In file included from include/linux/notifier.h:15:0,
from include/linux/memory_hotplug.h:6,
from include/linux/mmzone.h:718,
from include/linux/gfp.h:4,
from include/linux/irq.h:20,
from arch/mn10300/unit-asb2303/include/unit/timex.h:15,
from arch/mn10300/include/asm/timex.h:15,
from include/linux/timex.h:174,

from include/linux/timer.h:5,
from include/linux/workqueue.h:8,
include/linux/srcu.h:55:22: error: field 'work' has incomplete type
As a consequence, we do need a few more inclusions of <asm/irq.h>, namely
in arch/mn10300/unit-asb2303/smc91111.c and
arch/mn10300/unit-asb2305/unit-init.c.

Clear the interrupt mask registers of ASB2364 peripherals before enabling
interrupts so that any peripherals that weren't dealt with by the bootloader
after a reboot (if there was one) won't cause an interrupt storm when
interrupts are first enabled before the drivers are initialised.
Also, attempt to reset the peripherals attached to the FPGA.

Fix the ASB2364 gdbport UART register definitions. These registers are
actually 2 bytes apart, not 4 (which the ASB2303 and ASB2305 are).

Fix the definition of the ASB2364 FPGA IRQ detect registers. They accidentally
got defined to be the same as the mask registers when the patches were being
ported to the upstream kernel.

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.
