arm: ls1021aqds: Convert to driver model and enable serial support

Split duart configuration as device tree file. Move /chosen node
out of board commone device tree. Convert ls1021aqds nor and SD
configurations to driver model support (qspi already uses DM).
Enable ns16550 DM serial driver for nor configurations.
