memory savings (#3195) 

* d

* dead code

* all your ram are belong to me

* turn off gpiochips we don't need

* save

* save by using the same file handle

* smaller stack ok

* these can be on the stack

* this is closer

* what about ccm?

* probing available

* now probe ccm

* ccm

* put stuff in ccm

* fsio

* memory usage

* memory
