The imx-rngc driver binds to devices that are compatible to "fsl,imx25-rngb". Grepping through the device tree sources suggests this only exists on i.MX25. So restrict dependencies to configs that have this SoC enabled, but allow compile testing. For the latter additional dependencies for clk and readl/writel are necessary.
