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.
Fixes: cad2492de91c ("arm64: dts: st: Add SPI NOR flash support on stm32mp257f-ev1 board")

Changes in v2:
- Update commit message.
- Use correct memory-region-names value.
- Remove "Cc: <stable@vger.kernel.org>" tag as the fixed patch is not part of a LTS.
- Link to v1: https://lore.kernel.org/r/20250806-upstream_fix_dts_omm-v1-1-e68c15ed422d@foss.st.com

How LTS is relevant here?
