Impact: widen the reach of the low-memory-protect DMI quirk

Phoenix BIOSes variously identify their vendor as "Phoenix Technologies,
LTD" or "Phoenix Technologies LTD" (without the comma.)

This patch makes the identification string in the bad_bios_dmi_table
more general (following a suggestion by Ingo Molnar), so that both
versions are handled.

Again, the patched file compiles cleanly and the patch has been tested
successfully on my machine.
