Jett Rink c426be6ae2 arcada: add internal pull to ISH UART RX 
We do not want the RX signal to be floating on the board as that could
cause the ISH to remain in a higher power state (because there is logic
to keep the ISH in an higher power state when there is an active UART).

Add an internal 20K pull up on the RX line. In normal configuration this
will burn an additional 544uW.

BRANCH=R75
BUG=b:131241969
TEST=verify that ISH console still works with rework
