dts: nxp: mimxrt: Add missing jedec-id property to flash nodes

The spi-nor flash nodes require a jedec-id property as per the binding.
We add the jedec-id's as best we can determine based on the data sheets
for the various flash modules on these boards.

However these id's should be validated by actually reading the value to
ensure they are correct.
