If the PM related modules are not loaded and PM firmware not configured,
the system suspend fails to resume. Let's fix this by adding initial
platform_suspend_ops to block suspend and warn about missing modules.
When pm33xx and wkup_m3_ipc have been loaded and m3 coprocessor booted
with it's firmware, pm33xx sets up working platform_suspend_ops. Note
that we need to configure at least PM_SUSPEND_STANDBY to have
suspend_set_ops().

TEE/OP-TEE:
- Add tracepoints around calls to secure world
Memory controller drivers:

directly and reflect the drivers that don't fit into any other
subsystem as well as treewide changes for a particular platform.

issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
The header for arch/arm/mach-omap2/omap_twl.c follows this syntax, but the
content inside does not comply with kernel-doc.
This line was probably not meant for kernel-doc parsing, but is parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'), which
causes unexpected warning from kernel-doc:
"warning: wrong kernel-doc identifier on line:
* OMAP and TWL PMIC specific initializations."
Provide a simple fix by replacing this occurrence with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

We need to add a dummy smc call to the cpuidle wakeup path to force the
ROM code to save the return address after MMU is enabled again. This is
needed to prevent random hangs on secure devices like droid4.
Otherwise the system will eventually hang when entering deeper SoC idle
states with the core and mpu domains in open-switch retention (OSWR).
The hang happens as the ROM code tries to use the earlier physical return
address set by omap-headsmp.S with MMU off while waking up CPU1 again.
The hangs started happening in theory already with commit caf8c87d7f
("ARM: OMAP2+: Allow core oswr for omap4"), but in practise the issue went
unnoticed as various drivers were often blocking any deeper idle states
with hardware autoidle features.
This patch is based on an earlier TI Linux kernel tree commit 92f0b3028d9e
("OMAP4: PM: update ROM return address for OSWR and OFF") written by
Carlos Leija <cileija@ti.com>, Praneeth Bajjuri <praneeth@ti.com>, and
Bryan Buckley <bryan.buckley@ti.com>. A later version of the patch was

With the recent changes we are now booting am3/4, dra7, and omap4/5
without legacy data using devicetree, simple-pm-bus and genpd. Let's not
initialize and build the legacy data unless CONFIG_OMAP_HWMOD is selected
based on the SoCs enabled in .config.

We can now probe devices with ti-sysc interconnect driver and dts data.
Let's drop the related platform data and custom ti,hwmods dts property.
As we're just dropping data, and the early platform data init is based on
the custom ti,hwmods property, we want to drop both the platform data and
ti,hwmods property in a single patch.

We can now probe interconnects with simple-pm-bus and genpd.
Let's drop the legacy data along with the ti,hwmods property and flip
over to using simple-pm-bus instead of simple-bus.
