arm64: dts: ls1012a: Add QSPI node properties
Add support for QSPI on NXP layerscape LS1012A-RDB, LS1012A-QDS,
LS1012A-FRDM and LS1012A-FRWY boards.
LS1012A-RDB has 2 Spansion "s25fs512s" flashes of size 64M each and only
one can be accessed at a time.
LS1012A-QDS/FRDM has 1 spansion "s25fs512s" flash of size 64M.
LS1012A-FRWY has one winbond "w25q16dw" flash of size 2M.
Use generic compatibles as "jedec,spi-nor" for automatic detection of
flash. Configure RX and TX buswidth values as 2 as only two I/O lines are
available for data transfer.
Add ls1012a(si) node alongwith flash nodes.
