Most of these fixes were already submitted for old kernel versions, and were
approved, but for some reason they never made it into the releases.

Because this is a consolidation of a couple old missed patches, it touches both
Kconfigs and documentation texts.

Quoting Randy:

"It seems sad that this patch sources Kconfig.marker, a 7-line file,
20-something times.  Yes, you (we) don't want to put those 7 lines into
20-something different files, so sourcing is the right thing.

However, what you did for avr32 seems more on the right track to me: make
_one_ Instrumentation support menu that includes PROFILING, OPROFILE, KPROBES,
and MARKERS and then use (source) that in all of the arches."

Bugfixes for the OSK led support:

 - Fix Kconfig merge glitches:  Mistral handles idle and timer leds just fine
 - Fix pm_suspend() runtime botch:  can't sleep, so can't touch tps65010 leds

Improvements:
 - Switch sense of Mistral idle led, so idle == off

Probably the TPS65010 leds should be handled only by the "new led" API.

Support for generic input output for MX1 family.
The implementation prevents allocation of one pin
by two users, but does not store pointer to the user
description permanently, because this solution
would have bigger memory overhead.

The simple way to integrate code with per BSP
pins setup and allocation is required else all GPIO
registration checking is useless. The function
imx_gpio_setup_multiple_pins() can be used for this
purpose in future.

Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.

So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing.  Currently that's a bunch of
ARMs, and AVR32; more are on the way.

It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.

Enable svc access to cp6 via an undefined instruction hook.  Do not enable
access for usr code.

This patch also makes iop13xx select PLAT_IOP, this requires a small change
to drivers/i2c/busses/i2c-iop3xx.c.

Per Lennert Buytenhek's note, the cp6 trap routine is moved to arch/arm/plat-iop
Per Nicolas Pitre's note, the cp_wait is skipped since the latency to
return to the faulting function is longer than cp_wait.
