ENGR00292341 imx6sl hwrng
Add hwrng support for i.MX6SL.
1. Add RNG driver. This driver originated as fsl-rngc.c. It
has been modified to support device tree. The name has been
changed since it supports both b and c variants of RNG.
2. Added clock and compatible info to the device tree data.
3. Added the entry in the options in the Kconfig for hwrng.
