ARM: 6231/1: re-organize the nuc900 lcd arch platform data setting
Browse files Browse the repository at this point in the history
The patch re-organizes the nuc900 lcd arch platform data,
remove the lcd platform data setting from nuc950.c to dev.c

It can maximize the share codes between nuc900 series MCUs.
