arm64: dts: st: Add memory-region-names property for stm32mp257f-ev1

Browse Source 
In order to set the AMCR register, which configures the
memory-region split between ospi1 and ospi2, we need to
identify the ospi instance.

By using memory-region-names, it allows to identify the
ospi instance this memory-region belongs to.
