Subject: [PATCH 4/7] hwrng: omap3-rom - Initialize default quality to get data

Similar to commit 62f95ae805fa ("hwrng: omap - Set default quality")
we need to initialize the default quality for the RNG to be used.

The symptoms of this problem is that doing hd /dev/random does not
produce much data at all.
