The Arm True Random Number Generator Firmware, Interface 1.0, specification
defines an interface between an Operating System (OS) executing at EL1 and
Firmware (FW) exposing a conditioned entropy source that is provided by a
TRNG back end.

The edk2 patch series at:
https://edk2.groups.io/g/devel/topic/patch_v1_0_9_add_raw/85977024
adds RawAlgorithm support to RngDxe for Arm architecture using the Arm
FW-TRNG interface:

Ref: Bugzilla: 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668)

FW-TRNG interface service is already supported in TF-A for Juno. Therefore,
enable RNG support for Juno. Also, flink the NULL instance of TRNG library
for platforms that do not implement the FW-TRNG interface.

The changes can be seen at:
