rk3288: Add a config variable hack to skip display init
The current display init code causes Brain to crash when trying
to allocate resources. This just avoids doing display init if a
config variable is set. Once code has been implemented to properly
setup different types of displays we can get rid of this hack.
BUG=none
BRANCH=none
TEST=built and booted (to depthcharge) on Brain, compiled for
pinky with FEATURES=noclean and ensured config variable is 0
