[PATCH] hwrng: imx-rngc - setup default RNG quality

[Christian Eggers <ceggers@arri.de>]

When hw_random device's quality is non-zero, it will automatically fill
the kernel's entropy pool at boot.  For this purpose, one conservative
quality value is being picked up as the default value.

That happens when patches are sent upstream one year after writing....

Can you please add the third patch of the series?
