Ummmm....simply searching the web for " Package power limit notification" results in this Dell article
as the top result:

http://www.dell.com/support/article/us/ ... N266056/EN

A third workaround would be to use a newer kernel that does not spam the log with the harmless messages, but simply adding the kernel parameter to the boot command would be simplest.
