bootgraph.pl: relax timing information requirements
This patch removes the assumption of the bootgraph.pl script that the
timing information reported by PRINTK_TIME will contain at least one
entry with a time of less than 100 seconds.
Not all boards correctly reset the system timer and in many cases the
inital times reported by PRINTK_TIME is high. When this occurs the
bootchart.pl script fails to give any useful output.
This patch sets the $firsttime variable to the largest value expected
by PRINTK_TIME
