This is a simple move of all header files that are no longer
included by anything else from the include/mach directory
to the platform directory itself as preparation for
multiplatform support.
The mach/uncompress.h headers are left in place for now,
and are mildly modified to be independent of the other
headers. They will be removed entirely when ARCH_MULTIPLATFORM
gets enabled and they become obsolete.
Rather than updating the path names inside of the comments
of each header, I delete those comments to avoid having to
update them again, should they get moved or copied another
time.

As a preparation for multiplatform support, this moves all the
code using plat-orion over to use sparse irq support, which is
enabled implicitly for multiplatform.
In particular, the hardcoded NR_IRQS macro gets replaced with
a machine specific one that is set in the machine descriptor
in order to set up a static mapping for all legacy interrupts.

With the introduction of the ID based MBus API, it's better
to switch to use it instead of the current name based scheme.
This will allow to deprecate the name based API, once every
user is removed.

Preparing to move the parsing of reboot= to generic kernel code forces
the change in reboot_mode handling to use the enum.

This commit migrates the mach-orion5x platforms to use the mvebu-mbus
driver and therefore removes the Orion5x-specific addr-map code.
The dove_init_early() function now initializes the mvebu-mbus driver
by calling mvebu_mbus_init().
We also convert a number of orion5x_setup_xyz_win() calls to the
appropriate mvebu_mbus_add_window() calls, as each board was doing its
own setup for the NOR window or other devices. Ultimately, those
devices will be probed from the DT.
The common address decoding windows are now registered in the
orion5x_setup_wins() function. It is worth noting that the four PCIe
address decoding windows will ultimately no longer have to be
registered here: it will be done automatically by the PCIe driver once
Dove has been migrated to use the upcoming mvebu PCIe driver.

Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.
This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

Hook these platforms restart code into the new restart hook rather than
using arch_reset().
In addition, convert calls to arm_machine_restart() to orion5x_restart()
to ensure that they continue to work as intended.

This patch makes the various mach dirs that use the plat-orion time
code pass in timer and bridge addresses explicitly, instead of having
plat-orion get those values by including a mach dir include file --
the latter mechanism is problematic if you want to support multiple
ARM platforms in the same kernel image.

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]
