hwrng: imx-rngc - use devres for hwrng registration
Replace hwrng_register with devm_hwrng_register and let devres unregister our hwrng when the device is removed. It's possible to do this now that devres also handles clock disable+uprepare. When we had to disable+unprepare the clock ourselves, we had to unregister the hwrng before this and couldn't use devres. There's nothing left to do for imx_rngc_remove, this function can go.
