configs:  Review all implementations of board_lcd_initialize().  The NuttX convention is that all internal functions that return errors as an 'int' must return a negated errno value on failure and a non-negative value on success.  Most were right but eight of them had cloned logic that returns 1 on success and zero on failure... both of which are interpreted as success by the caller since they are non-negative.
