Building omap_devices should only be done at init time, and since
omap_device_build() is using early_platform calls which are also
__init, this ensures that omap_device isn't trying to use functions
that disappear.

All of the device init and device driver interaction with omap_device
is done using platform_device pointers.  To make this more explicit,
have omap_device return a platform_device pointer instead of an
omap_device pointer.

All current users of the omap_device pointer were only using it to get
at the platform_device pointer or struct device pointer, so fixing all
of the users was trivial.

This also makes it more difficult for device init code to directly
access members of struct omap_device, and allows for easier changing
of omap_device internals.

Start cleaning up the voltage layer to have a voltage domain layer
that resembles the structure of the existing clock and power domain
layers.  To that end:

- move the 'struct voltagedomain' out of 'struct omap_vdd_info' to
  become the primary data structure.

- convert any functions taking a pointer to struct omap_vdd_info into
  functions taking a struct voltagedomain pointer.

- convert the register & initialize of voltage domains to look like
  that of powerdomains

- convert omap_voltage_domain_lookup() to voltdm_lookup(), modeled
  after the current powerdomain and clockdomain lookup functions.

- omap_voltage_late_init(): only configure VDD info when
  the vdd_info struct is non-NULL

At this point in time, there's no reason for this header file to be in
plat-omap/include/plat/voltage.h.  It should not be included by device
drivers, and the code that uses it is currently all under mach-omap2/.

There's no reason for this header file to be in
plat-omap/include/plat/smartreflex.h.  The hardware devices are in
OMAP2+ SoCs only.  Leaving this header file in plat-omap causes
problems due to cross-dependencies with other header files that should
live in mach-omap2/.

Thanks to Benoît Cousson <b-cousson@ti.com> for suggesting the removal
of the smartreflex.h include from the OMAP3xxx hwmod data.

omap_enable_smartreflex_on_init is meant to be used by boards
which would like to have SR enabled by default on the platform, while
omap_devinit_smartreflex is used by pm code, the protos are defined
in pm.h. This header should be included to ensure that sr_device
function definitions match the prototypes.

including pm.h fixes the sparse warnings (with CONFIG_OMAP_SMARTREFLEX=y):
arch/arm/mach-omap2/sr_device.c:138:13: warning: symbol 'omap_enable_smartreflex_on_init' was not declared. Should it be static?
arch/arm/mach-omap2/sr_device.c:143:12: warning: symbol 'omap_devinit_smartreflex' was not declared. Should it be static?

This patch extends the smartreflex framework to support
OMAP4. The changes are minor like compiling smartreflex Kconfig
option for OMAP4 also, and a couple of OMAP4 checks in
the smartreflex framework.

The change in sr_device.c where new logic has to be introduced
for reading the efuse registers is due to the fact that in OMAP4
the efuse registers are 24 bit aligned. A __raw_readl will
fail for non-32 bit aligned address and hence the 8-bit read
and shift.

This patch adds support for device registration of various
smartreflex module present in the system. This patch introduces
the platform data for smartreflex devices which include
the efused n-target vaules, a parameter to indicate
whether smartreflex autocompensation needs to be
enabled on init or not. An API
omap_enable_smartreflex_on_init is provided for the
board files to enable smartreflex autocompensation during
system boot up.
