a couple consistent misspellings that could be fixed

[Robert P. J. Day]

  being the pedant that i am, i notice the following widespread
misspellings in the barebox codebase:

* "existance" (should be existence)

  actually, not that widespread, only three, all comments so easy to
fix

* "persistant" (should be persistent)

  this one is much uglier -- a couple dozen, including its use in
runnable code itself. just run:

  $ grep -r persistant *

to see what i mean.

  what's the policy for fixing a spelling error that spills over from
the comments into compilable code itself?
