PATCH v2 1/1 arm64: dts: imx8mm: imx8mp: Update EEPROM with nWP GPIO, label and layout

Describe ID EEPROM nWP GPIO, label and nvmem layout. The i.MX8MM eDM SBC and i.MX8MP eDM SBC nvmem layout is almost identical, except for length of product-name@32 field, which is 19 Bytes on the Mini and 24 Bytes on the Plus.
