02d249f99e rng: meson: make core clock optional
This fixes HWRNG support on Amlogic GXL, GXM, G12A, G12B & SM1
based boards dues to the lack of the core clock in the device tree.

It was reported breaking EFI boot in the Linux EFI stub, because the
EFI_RNG_PROTOCOL didn't check for the RNG device presence before
installing itself.

The Linux amlogic,meson-rng.yaml doesn't mandate the core clock,
this the clock should be ignores if not present.

Nevertheless, the clock should be present and this should be fixed
on the Linux meson-gxl.dtsi & meson-g12-common.dtsi then synced
with U-Boot.

The change has been tested on a Khadas VIM3, which uses the common
meson-g12-common.dtsi like the Odroid-C4 & Odroid-N2 in Scott's
report, along with the RNG cmd.

90526e9fba common: Drop net.h from common header
Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

Note that this net.h header itself has quite a lot in it. It could be
split into the driver-mode support, functions, structures, checksumming,
etc.

c312c4b4dc drivers/rng: simplify Kconfig
For all sandbox systems with DM_RNG we enable RNG_SANDBOX. So we can simply
set the default to yes.

All rng drivers depend on DM_RNG. Use a single 'if' instead of individual
dependencies. Now 'make menuconfig' shows the individual drivers neatly
indented under the DM_RNG entry.
