Keith Packard [Sat, 21 Aug 2021 04:20:59 +0000 (21:20 -0700)]
Move reset_n to LPC PIO0_4, a true open-drain pin
There are two pins on the LPC which operate in true open-drain mode,
PIO0_4 and PIO0_5. Use one of these instead of one of the 'pseudo open
drain' pins to make sure reset works correctly.
