[3.18.3 BISECTED REGRESSION] scx200_acb / cs5535-smb / geodewdt / cs5535-clockevt torpedoed

[Nix <nix@esperi.org.uk>]

As of 3.18.3, the watchdog timer, high-res timers, etc on my Soekris
net5501 no longer work.

dmesg says:

    PCI: Restore detection of read-only BARs

    commit 36e8164882ca6d3c41cb91e6f09a3ed236841f80 upstream.

before which everything works OK. (Bisection confirmed by reverting this
commit, following which everything works again.)

A diff between good and bad boot output is not very edifying: all we
really see is ordering differences, address differences and things
dropping out of the log because of the absent hardware (mostly, I think,
the different time source because we're forced to fall back to the PIT
rather than using the nice fast cs5535-clockevt):
