Board related changes for v3.10 merge window. These are pretty
much all non-critical fixes for platform device initialization
that will be needed until we can drop the board-*.c files and
move to DT based boot.

Clean-up for omap2+ timers from Jon Hunter <jon-hunter@ti.com>:
This series consists mainly of clean-ups for clockevents and
clocksource timers on OMAP2+ devices. The most significant change
in functionality comes from the 5th patch which is changing the
selection of the clocksource timer for OMAP3 and AM335x devices
when gptimers are used for clocksource.
Note that this series depends on 7185684 (ARM: OMAP: use
consistent error checking) in RMK's tree and 960cba6 (ARM:
OMAP5: timer: Update the clocksource name as per clock data)
in omap-for-v3.10/fixes-non-critical. So this branch is based
on a merge of 7185684 and omap-for-v3.10/fixes-non-critical
to avoid non-trivial merge conflicts.

This patch is V3 of a GPIO driver for the R-Car series of
SoCs from Renesas. This driver is designed to be reusable
between multiple SoCs that share the same basic building block,
but so far it has only been used on R-Car H1 (r8a7779).
Each driver instance handles 32 GPIOs with individually
maskable IRQs. The driver operates on a single I/O memory
range and the 32 GPIOs are hooked up a single interrupt.
In the case of R-Car H1 either external IRQ pins or GPIOs
with interrupts can be used for on-board interupts. For
external IRQs 4 pins are supported, and in the case of GPIO
there are 202 GPIOS as 202 interrupts hooked up via 6 driver
instances and to the GIC and the Cortex-A9 Quad.
At this point this driver is interfacing as a regular
platform device driver. In the future DT support will be
submitted as an incremental feature patch.

Stop checking for pin availability in direction and get functions.
These functions can be called repeatedly, so checking every time is
bad for performance. Now that requesting GPIO pins is no longer
optional, checking for availability at pin request time is enough.

Per Documentation/gpio.txt, gpio_request callbacks should return 0 on
success or a negative value on error. So it is not clear what was
meant by letting ichx_gpio_request return 1 in some cases, nor how a
caller would interpret it.
Align the code with the comment above it and consider pins as
available by default.
