Replace ppc4xx-specific MMIO accessors with portable helpers and
fix two high-severity timer bugs: a UAF on module exit (timer
fires after iounmap) and a close race that defeats the watchdog
reset on unexpected daemon termination.

v2: fix preexisting issues

Rosen Penev (2):
  watchdog: pika_wdt: fix timer leak and close race
  watchdog: pika_wdt: replace in_be32/out_be32 with
    ioread32be/iowrite32be
