[PATCH] fireware: add NO_MSI quirks for o2micro controller

[ming.lei at canonical.com]

From: Ming Lei <tom.leiming at gmail.com>

This patch fixes the bug 801719, and the maintainer
(stefan-r-ubz at s5r6.in-berlin.de) of firware subsystem
is submmitting the patch on upstream kernel.

SRU Justification:

Impact:
        - without the patch, Firewire and SD card are not both
        working on Dell E5420/E5420m/E5520/E5520M/E6520/M6600/M4600.
Fix:
        - After applying the patch, Firewire and SD card are both
        working now.
