[v2,0/6] hwrng: imx-rngc - use polling instead of interrupt

Message

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.

v2:
- set reasonable timeouts
- separate commit for the removal of interrupt handling
- readl_poll_timeout does not wait in the foreground

Martin Kaiser (6):
  hwrng: imx-rngc - reasonable timeout for selftest
  hwrng: imx-rngc - reasonable timeout for initial seed
  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 for initial seed
  hwrng: imx-rngc - remove interrupt handler
