[PATCH] arm64: dts: imx8mm: imx8mp: Update EEPROM with nWP GPIO, label and layout

[Marek Vasut]

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.
