[PATCH 1/3] misc: atsha204a: remove broken for loop

["Michał Barnaś" <barnas@google.com>]

Some previous commit changed the continue statement to return,
making the for loop used to retry waking up the chip to always
return after one iteration. This commit removes the loop, cleaning
the code a little.
