x86: tsc: Remove unneeded DMI-based blacklisting
The blacklist was added in response to my bug report (http://lkml.org/lkml/2006/1/19/362) and has never contained more than the one entry describing my old now dead ThinkPad 380XD laptop. As found out later (http://lkml.org/lkml/2007/11/29/50), this special treatment has been unnecessary for a long time, so it can be removed.
