From: Sasha Levin

From: Andrey Smirnov <andrew.smirnov@xxxxxxxxx>

[ Upstream commit cd58a174e58649426fb43d7456e5f7d7eab58af1 ]

RDU2 production units come with resistor connecting WP pin to
correpsonding GPIO DNPed for both SD card slots. Drop any WP related
configuration and mark both slots with "disable-wp".
