ARM: dts: renesas: rskrza1: Add FLASH nodes 



Add device nodes for the dual Spansion S25FL512S QSPI NOR FLASH and the
Spansion S29GL512S CFI NOR FLASH on the RSK+RZA1 development board.
The former is mapped directly through the SPI Multi I/O Bus Controller.
The latter resides in the external address space of the Bus State
Controller (BSC).
