[PATCH] Use read-only mappings for DMI tables everywhere.

[Stefan Tauner]

R/W mappings cause explosions sometimes.

Signed-off-by: Stefan Tauner

Simply rename (and refine) physmap_round to physmap_ro_round because dmi
is the only user anyway.

The patch was tested on real hardware that had problems without it.
W/o patch:

With patch:
http://paste.flashrom.org/view.php?id=1990

Without vetoes I will commit this soonish.
