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.
