Subject: [PATCH] crypto: caam: set hwrng quality level

When quality is set to 0 this driver is not used as randomness source by
HWRNG framework at all. So set the quality and finally make this driver
work. The value of the quality was discussed before
( see https://patchwork.kernel.org/patch/9850669/ ) and it is still a rough
value.
