When creating the DT based boards-ts219.c the none DT ts219-setup.c
was used as a template. This includes a lateinit() call to initialize
the PCIe bus. The code makes use of machine_is_ts219() which is never
true on DT, so a FIXME was added and the code left as is. This was
unproblematic until b73690c8: "ARM: Kirkwood: Support basic
hotplug for PCI-E" which changes the way the PCIe bus is
initialized. The non-DT ts219-setup.c now crashes during boot.  The
lateinit() call in the DT boards-ts219.c is being called,
machine_is_ts219() is true and so the PCIe is initialized a second
time.

This patch removes the useless, and now clearly dangerous, code from
boards-ts219.c, making ts219-setup.c work again.

The two different variants of QNAP TS devices, varying by SoC, put the

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.

chip (TS-119P+, TS-219P+ and TS-419P+).  The differences to the 6281

 - Ethernet PHY address
 - GPIOs used for buttons (TS-119P+/TS-219P+)

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 }'

MPP44 can be used to differentiate between one-bay (TS-11x) and
two-bay (TS-21x) devices.

According to an engineer from QNAP, the setting of MPP44 depends
on the firmware rather than hardware.  Presumably, this means
that you could fake the MPP44 value by changing the boot loader.

MPP36 is used on the QNAP TS-11x/TS-21x devices to indicate how
much RAM there is: it's high for 512 MB RAM (TS-x19) and low for

it for completeness.
