ARM: orion5x: convert DT to use the mvebu-mbus driver
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.
