We are now booting all mach-omap2 in device tree only mode.
Any code that is only called in legacy boot mode where
of_have_populated_dt() is not set is safe to remove now.

Note that omap_init_sti() won't do anything so we can
remove omap2_init_devices() as pointed out by Sebastian
Reichel <sebastian.reichel@collabora.co.uk>.

I found this section mismatch when building with an older
compiler release:

WARNING: vmlinux.o(.text+0x3051c): Section mismatch in reference from the
function omap_init_rng() to the function .init.text:omap_device_build()

Obviously this one function should be __init as well. Normally
we don't get a warning as the function gets inlined into its
caller.

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.

The legacy-style mailbox device creation is supported currently
only for OMAP3, as all other SoCs are DT-boot only. Even on this
SoC, there are no client drivers that utilize these mailbox devices.
So, clean up the legacy-style mailbox device instantiation logic.
The mailbox devices are already present and supported for the DT
boot on OMAP3.

This will us allow to just move gpmc.c to live under drivers
in the next patch.

Note that we now also remove the omap specific check for the
initcall. That's OK as gpmc_probe() checks for the pdata
and bails out for other platforms compiled in.

Also the postcore_initcall() maybe possible to change to
just regular module_init(), but let's do that in separate
patch after the move to drivers is done.

The omap2 camera driver has been deprecated for a year and is now
going to be removed. It is unmaintained and it uses an internal API
that has long since been superseded by a much better API. Worse, that
internal API has been abused by out-of-kernel trees (i.MX6).

In addition, Sakari stated that these drivers have never been in a
usable state in the mainline kernel due to missing platform data.

Omap4 and later have been booting in device tree only
mode for quite some time now. This initcall is no longer
needed. Note that omap3 uses a different driver omap_l3_smx,
and the initcall for that one is still needed until omap3
boots in device tree only mode.
Signed-off-by: NTony Lindgren <tony@atomide.com>

When booting omap3 in device tree mode, we're currently getting
the following errors:

omap_l3_smx omap_l3_smx.0: couldn't request debug irq
omap_l3_smx: probe of omap_l3_smx.0 failed with error -22

This is because we don't have handling in the driver for the
compatible property and instead assume platform data being
passed.

Note that this binding is already documented, and implemented
for the related omap_l3_noc driver for omap4 and later. Looks
like the binding somehow never got never implemented for this
omap_l3_smx driver though.

Let's also remove __exit_p to allow binding and unbinding
of the driver while at it.

The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.

The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).

As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
  and private header files. The public header has only the API related
  functions and types.
- The module name mailbox.ko from plat-omap is changed to
  omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
    mailbox_omap1.ko for OMAP1
    mailbox_omap2.ko for OMAP2+

mailbox driver. This data is now represented in a concise format
and moved to the respective omap_hwmod data files and published
to the driver through the platform data.
