This commit converts the LaCie d2 Network platform to the Device Tree.

All devices except LEDs are converted, because the LED code needs a
non-LED GPIO to be set to a given value for the LEDs to work, and this
cannot yet be easily represented in DT.

Also, references to the LaCie Big Disk Network platform are lost,
because this platform apparently has exactly the same hardware support
as the LaCie d2 Network, so their Device Tree files would be
identical.

This commit converts the RD-88F5182 platform to the Device Tree. All
devices except the PCI are converted to the Device Tree.

It is worth noting that:

 * The PCI description for the DT case is kept in board-rd88f5182.c.

 * The existing non-DT support in rd88f5182-setup.c is kept as is, in
   order to allow testing of a given platform in both DT and non-DT
   cases. It will ultimately be removed, once we no longer care about
   non-DT support for Orion5x.

This commit switches the Orion5x platforms described through DT to use
a DT-defined interrupt controller and timer.

This involves:

 * Describing in the DT the bridge interrupt controller, which is a
   child interrupt controller to the main one, which is used for timer
   and watchdog interrupts.

 * Describing in the DT the timer.

 * Adding in the DT the interrupt specifications for the watchdog.

 * Selecting the ORION_IRQCHIP and ORION_TIMER drivers to be compiled.

 * Change board-dt.c to no longer have an ->init_time() callback,
   since the default callback will work fine: it calls
   clocksource_of_init() and of_clk_init(), as needed.

 * Implement a multi-IRQ handler for non-DT platforms in
   mach-orion5x/irq.c.

Until the previous commit, the Orion5x clocks were not described in
the Device Tree. Now that they are described in the Device Tree, we
can replace the manual 'clock-frequency' property in the UART nodes
by a nicer 'clocks' reference in those UART nodes.

This commit consequently removes the 'clock-frequency' property from
the LaCie edmini_v2 board, which is at this point the only Orion5x
board converted to the Device Tree.

 * Selects ORION_CLK to enable the compilation of the clock driver.

 * Call of_clk_init() instead of the Orion5x-specific clock

This commit switches the Orion5x Device Tree files to use the DT
representation and probing for the mvebu-mbus driver. The changes are
mainly:

 * Re-organize the DT to follow the same organization as the one used
   on Armada 370/XP, which is needed for mvebu-mbus to work: a
   top-level soc { ... } node, which corresponds to the MBus bus, and
   a sub-node internal-regs { ... } for all peripherals whose register
   sit only in the "Internal Register Window". This change re-indents
   by one level the definition of all nodes in the Device Tree, which
   explains the large change.

 * Use custom functions orion5x_dt_init_early() and
   orion5x_dt_init_time() instead of orion5x_init_early() and
   orion5x_timer_init() as we now want the MBus driver to be probed
   from the Device Tree. We still use the old-style timer
   initialization, but that will be changed in a followup commit.

The interrupt controller node was located outside of the ocp@f1000000
node, which doesn't make much sense: like any other device, the
interrupt controller has registers located in the "Internal Registers
Window", so it is much more logical to have it under the ocp@f1000000
node.

It is even more important as we are going to move Orion5x to use the
Device Tree binding of the mvebu-mbus driver.
