IRC change: private #pm to freenode #linaro-pm

Hi Gang,

FYI

Effective immediately #pm on the private IRC server is deprecated. Please move over to #linaro-pm on Freenode.

We were using the private #pm to talk about operational items and potentially some confidential landing team items. For the last few months all of the discussion has not contained any material which contractually needs to remain private so in the interest of transparency I'm forcing the channel over to Freenode. As with all public channels, everyone is welcome to join and participate.

Joey
