Rockchip SoCs used to have a random number generator as part of their
crypto device, and support for it has to be added to the corresponding
driver.
Newer Rockchip SoCs like the RK3568 have an independent True Random
Number Generator device. Import pending patchset which adds a driver for
it, include it in Kconfig and enable it in the device tree.
Doing so significantly reduces the time needed to boot devices based on
those SoCs, from about 27 seconds until Ethernet is up and running to
less than 13 seconds with a minimal snapshot image.

This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.
The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.
