Memory controller drivers for v5.11 - Tegra SoC, part two

Continuation of work on Tegra SoC memory controllers towards adding
interconnect support and integration with devfreq.

This brings few more patches including one which removes/fixes annoying
warning if the DTS patches get applied.  This is expected and only
informs that new features of Tegra memory controller drivers will not be
enabled however the warning itself could look worrying.

Reset controller updates for v5.11

This tag adds support for sharing pulsed resets under certain
conditions. For example, when multiple drivers go through a
suspend-resume cycle, a reset line they share can be triggered
again during resume.
Further, the reset-meson driver now can be built as a module, the
reset-socfpga driver properly releases its memory region in the
probe error path, and reset-ti-syscon driver uses regmap_write_bits()
instead of regmap_update_bits() to support devices without status
readback.

Driver changes for omaps for genpd for v5.11 merge window

This series of changes allows booting am335x with genpd and
device tree data without the legacy platform data. Also at
least am437x can be booted with gendp with power domain and
dts data. The SoC specific dts changes will be a separate
pull request.

We need the following driver changes merged before the dts
changes can be done:

- platform code needs a few improvments to probe l4_wkup first
  for clocks, and to bail out when there is no platform data

- ti-sysc driver needs a non-urgent fix for asserting rstctrl
  reset only after disabling the clocks, to probe modules with
  no known control registers, and added quirk handling for gpmc
  devices

- omap-prm driver needs a non-urgent fix for reset status bit,
  support added for pm_clk, and then we add the rest of am335x
  power domain data

- clock driver for am335x needs to keep l3_main clock enabled
  with genpd for suspend and resume to work

- wkup_m3 remoteproc driver needs support added for reset
  control if available instead of the legacy pdata callbacks

- pm33xx driver needs PM runtime support added for genpd

The am335x specific driver changes for the clock, wkup_m3,
pm33xx and remoteproc drivers are quite trivial and have not
caused merge conflicts in Linux next. I did not get acks for
these changes except from Santosh but had already pushed out
the branch already at that point. So I've added the related
driver maintainers to Cc.

In the error path of rpcif_manual_xfer() the value of ret is overwritten
by value returned by reset_control_reset() function and thus returning
incorrect value to the caller.

This patch makes sure the correct value is returned to the caller of
rpcif_manual_xfer() by dropping the overwrite of ret in error path.
Also now we ignore the value returned by reset_control_reset() in the
error path and instead print a error message when it fails.

For the common platform_get_resource()+devm_platform_ioremap() combination,
there is a helper, so use it and make the code a bit more compact.

MediaTek bus fabric provides TrustZone security support and data
protection to prevent slaves from being accessed by unexpected
masters.
The security violation is logged and sent to the processor for
further analysis or countermeasures.

Any occurrence of security violation would raise an interrupt, and
it will be handled by mtk-devapc driver. The violation
information is printed in order to find the murderer.

For each client driver, its timeout handler need to dump hardware register
or its state machine information, and their way to detect timeout are
also different, so remove timeout handler in helper function and
let client driver implement its own timeout handler.
