Pull SoC driver updates from Arnd Bergmann:
"This is the first half of the driver changes:
- A treewide interface change to the "syscore" operations for power
management, as a preparation for future Tegra specific changes
- Reset controller updates with added drivers for LAN969x, eic770 and
RZ/G3S SoCs
- Protection of system controller registers on Renesas and Google
SoCs, to prevent trivially triggering a system crash from e.g.
debugfs access
- soc_device identification updates on Nvidia, Exynos and Mediatek
- debugfs support in the ST STM32 firewall driver
- Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI
- Cleanups for memory controller support on Nvidia and Renesas"

- Fix bounds checking of address properties in FDT code. Rework the
code to have a single implementation of the bounds checks.
- Rework of_irq_init() to ignore any implicit interrupt-parent (i.e.
in a parent node) on nodes without an interrupt. This matches the
spec description and fixes some RISC-V platforms.

It turns out that the change in commit 76934e495cdc ("cpuidle: Add
sanity check for exit latency and target residency") goes too far
because there are systems in the field on which the check introduced
by that commit does not pass.
For this reason, change __cpuidle_driver_init() return type back to void
and make it print a warning when the check mentioned above does not
pass.

The CPU system wakeup QoS limit must be respected for the regular cpuidle state selection. Therefore, let's extend the common governor helper cpuidle_governor_latency_req(), to take the constraint into account.
