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.

for DSPI flash
The type of DSPI flash on ls1021aqds is AT45DB021, it has specail
commands and page-size.
Use the special spi flash driver instead of "spi_flash_std" driver.

Update DSPI controller node in ls1021a.dtsi.
Update flash device node in ls1021a-qds.dts.
Ls1021a-twr board doesn't support DSPI, so remove DSPI node
in ls1021a-twr.dts.

Change address_cells and size_cells of root node and 'soc' node
from 2 to 1.
We backport ls1021a device tree source files from kernel to u-boot.
Kernel files set address_cells and size_cells to 2 in order to access
more than 4GB space.
But we don't have this requirement now and u-boot fdtdec_get_xxx interfaces
can't support property whose size is 'u64' completely.
So make this change.

Bring in required device tree files for ls1021a from Linux.
These are initially unchanged and have a number of pieces not needed by U-Boot.
