The achievable power modes of the power domains in cpuidle
depends on the system wide 'enable_off_mode' knob in debugfs.
Upon changing enable_off_mode, do not change the C-states
'valid' field but instead dynamically restrict the power modes
when entering idle.

The C-states 'valid' field is just used to enable/disable some
C-states at init and shall not be changed later on.

The current implementation defines an internal structure and a
C-states array. Using those structures is redundant to the
structs used by the cpuidle framework.

This patch provides a clean-up of the internal struct, removes the
internal C-states array, stores the data using the existing cpuidle
per C-state struct and registers the mach specific data to cpuidle
C-state driver_data (accessed using cpuidle_[gs]et_statedata).
Also removes unused macros, fields and code and compacts the repeating
code using an inline helper function.

The result is more compact and more readable code as well as
reduced data RAM usage.

Also retain C1 as the only always valid C-state and system safe state.

Currently, omap_display_init() maintains arrays for hwmod name(oh_name) and the
correspnding platform_device name(dev_name) needed by omap_device_build().
A variable oh_count keeps a track of the number of devices to build from oh_name
based on what omap revision it is.

Clean this up by maintaining an array of omap_dss_hwmod_data struct which is
defined for each omap revision as suggested by Tomi Valkeinen. Assign the
corresponding omap_dss_hwmod_data array struct to the pointer curr_dss_hwmod in
omap_display_init().

In commit 7538e3db (PM: add support
for device power domains) a better way for handling platform-specific
power hooks was introduced.

Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.

Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

[rjw: Rebased on top of a previous change modifying the handling of
 power domains by the PM core so that power domain callbacks take
 precendence over subsystem-level PM callbacks.]

Blindly setting 1.2V in the initial structure may not even match the
default voltages stored in the voltage table which are supported for
the domain. For example, OMAP3430 core domain does not use 1.2V and
ends up generating a warning on the first transition.

Further, since omap2_set_init_voltage is called as part of the pm
framework's initialization sequence to configure the voltage required
for the current OPP, the call does(and has to) setup the system
voltage(curr_volt as a result) using the right mechanisms appropriate
for the system at that point of time. This also overrides
initialization we are currently doing in voltage.c making it
redundant. So, remove the wrong and redundant initialization.
