From: Philippe Schenker <philippe.schenker@xxxxxxxxxxx>
Due to many carrier boards pulling the usdhc1 signals up to 3.3 volt we
need to disable 1.8 volt signaling. Adding the no-1-8-v property
basically disables UHS-I modes by default.
Also pull-up the command and data lines to the +V3.3_1.8_SD rail and
set them to the 200 MHz speed grade (e.g. pinmux bits 7-6: meaning 11
SPEED_3_max_200MHz).
Explicitly specify a bus-width of <4> in the module-level device tree
include file and drop the no-1-8-v property from the carrier boards
device trees.
