Remove the OMAP-specific PM debug 'sleep_while_idle' feature which is
currently available as an OMAP-specific debugfs entry.

This duplicates existing ARM-generic functionality available as a
boot-time option using the boot cmdline option 'hohlt'.

If runtime configuration of this is needed, then adding a debugfs
entry for the ARM-generic hlt/nohlt interface should be added.

We will enable and disable interrupt on a need basis in the class
driver. We need to keep the IRQ disabled by default else the
forceupdate or vcbypass events could trigger events that we don't
need/expect to handle.

This is a preparation for SmartReflex AVS class drivers such as
class 2 and class 1.5 which would need to use interrupts. Existing
SmartReflex AVS class 3 driver does not require to use interrupts
and is not impacted by this change.

Interrupt notification mechanism of SmartReflex can be used by the
choice of implementation of the class driver. For example, Class 2 and
Class 1.5 of SmartReflex can both use the interrupt notification to
identify the transition of voltage or other events.

Hence, the actual class does not matter for notifier. Let the class
driver's handling decide how it should be used. SmartReflex driver
should provide just the primitives.

When runtime PM is disabled, device clocks need to be enabled on
device add and disabled on device remove.  This currently is not
happening because in the !PM_RUNTIME case, no notifiers are registered
for OMAP1 devices.

Fix this by ensuring notifiers are registered, even in the !PM_RUNTIME case.

Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.

To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.

The V28_A domain in Nokia N900 that supplies VDD voltages to TLV320AIC34 and
TPA6130A2 should not be shutdown. This is because otherwise there will be
leak from VIO to VDD in TLV320AIC34 and this leak consumes more battery
current that is saved from keeping V28_A off. With this patch the battery
current consumption is approximately 1.5 mA lower.

ads7846 driver can use either gpio_pendown or get_pendown_state()
callback. In case of gpio_pendown, it requests the provided gpio_pendown
thus resulting in double requesting that gpio:

Fix this by restricting the gpio request to the case of
