I Research a lot for this and trust me I'm telling you the best solution as per my knowledge and research.
go to your profile- click on activity log- click on likes- it will list out your all likes then unlike the Facebook pages with single click for all.

there is no way to do things on facebook "all at once" like you want to do

the best option is to use your activity log
