Switch the "logicoreip" registers to the new xlnx,vcu-settings binding

If the driver is not able to find a node with the new binding, fall back

The xlnx,vcu binding comprises two adjacent register banks:
The first register bank ("vcu_slcr") contains registers for setting the
clocks of the vcu and controlling the performance monitors. The second
bank ("logicoreip") contains the configuration settings of the video codec
unit, which are set before synthesizing the bitstream.
Drivers that drive the actual video codec unit need to read the
registers from the logicoreip register bank for configuring the vcu
firmware.
As logicoreip is a too generic name for this register bank, use
"vcu-settings" as a binding name, because the register bank basically
provides the configuration settings of the VCU.
Therefore, add the vcu-settings binding to provide a syscon interface
for other drivers to read these registers.
The alternative would have been to merge the two register banks of the
xlnx,vcu binding into one register bank and make xlnx,vcu provide a
syscon interface, but that would lead to more incompatibility than
making second register bank of xlnx,vcu optional.

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.

The Exynos ChipID driver on Exynos SoCs has only informational
purpose - to expose the SoC device in sysfs. No other drivers
depend on it so there is really no benefit of initializing it early.
Instead, initialize everything with arch_initcall which:
1. Allows to use dev_info() as the SoC bus is present (since
core_initcall),
2. Could speed things up because of execution in a SMP environment
(after bringing up secondary CPUs, unlike early_initcall),
3. Reduces the amount of work to be done early, when the kernel has to
bring up critical devices.

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.

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.
