The long term solution is to allow passing options to the hwmod framework to not reset pins from both board-*.c files and from cmdline. For this case it would be nice to pass info from the board-*.c file to hwmod so it knows to skip reset only for this GPIO. For booting Linux from other OS, something like hwmod.reset_disable=all is needed to keep the LCD on.
