Use polling and wait actively for the self test and the initial seeding
of the rngc to complete. This is much simpler than using an interrupt
and a completion. Also, there's nothing we can do in parallel while self
test or initial seeding are running.

  hwrng: imx-rngc - use polling to detect end of self test
  hwrng: imx-rngc - read status register for error checks
  hwrng: imx-rngc - use polling to wait for end of seeding
