Andre Przywara 31565bb0aa driver: rng: Add DM_RNG interface for ARMv8.5 RNDR registers 
The ARMv8.5 architecture extension defines architectural RNDR/RNDRRS
system registers, that provide 64 bits worth of randomness on every
read. Since it's an extension, and implementing it is optional, there is
a field in the ID_AA64ISAR0_EL1 ID register to query the availability
of those registers.

Add a UCLASS_RNG driver that returns entropy via repeated reads from
those system registers, if the extension is implemented.
The driver always binds, but checks the availability in the probe()
routine.

This helps systems which suffer from low boot entropy, since U-Boot can
provide entropy via the generic UEFI entropy gathering protocol to the OS,
at an early stage.
