Rob Herring has done a sweeping change cleaning up all of the mach/io.h includes,
moving some of the oft-repeated macros to a common location and removing a bunch of
boiler plate. This is another step closer to a common zImage for multiple platforms.

Fix up various fairly trivial conflicts (<mach/io.h> removal vs changes

Several platforms incorrectly use __io() for casting to 'void __iomem *'.
This converts all of those uses to use the common IOMEM macro.

This patch updates the Kota2 board support code to
use the recently merged TPU LED driver whenever
possible.
The sh73a0 SoC has 5 TPU hardware blocks each with
4 timer channels which in theory allows a total of
20 LEDs to be controlled by "leds-renesas-tpu"
driver instances. The Kota2 board has 4 LEDs connected
to GPIO pins that also come with TPU pin functions, so
this patch ties up these 4 LEDS and leaves the remaining
3 LEDS for the GPIO based LED driver.

Fix IRQ support on the Kota2 board. The sh73a0 and the Kota2
board make use of the ARM GIC hardware block as main interrupt
controller. The following commit changed the default behaviour
for non-device tree platforms and broke Kota2 irq support:

Support PINT on sh73a0 and Kota2 using INTC PINT macros.
With this patch applied the Kota2 ethernet is handled
through one of the chained sh73a0 PINT interrupt controllers.
sh73a0 PINT support is included in 3.2-rc but the Kota2 board
code does not make use of this shared code base without this
patch. Without this patch kota2 on-board ethernet is broken.
