Changes optee_rng driver to register itself has a OP-TEE service so
that a device is bound for the driver when OP-TEE enumerates the
PTA RNG service.

The TPM device has a builtin random number generator(RNG)
functionality. Expose the RNG functions of the TPM device to the
driver model so that they can be used by the EFI_RNG_PROTOCOL if the
protocol is installed.
Also change the function arguments and return type of the random
number functions to comply with the driver model api.

Adds random number generator driver using Arm SMCCC TRNG interface to
get entropy bytes from secure monitor. The driver registers as an
Arm SMCCC feature driver to allow PSCI driver to bind a device for
when secure monitor exposes RNG support from Arm SMCCC TRNG interface.

Add driver for OP-TEE based Random Number Generator on ARM SoCs
where hardware entropy sources are not accessible to normal world
and the RNG service is provided by a HWRNG Trusted Application (TA).
This driver is based on the linux driver: char/hw_random/optee-rng.c

This adds a helper function for clk_get_by_name in cases where the clock is
optional. Hopefully this helps point driver writers in the right direction.
Also convert some existing users.

This name is far too long. Rename it to remove the 'data' bits. This makes

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

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.

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.

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.
