Janne Grunau 3febe9de5c arm64: dts: apple: Add SPI NOR nvram partition to all devices
All known M1* and M2* devices use an identical SPI NOR flash
configuration with a partition containing a non-volatile key:value
storage. Use a .dtsi and include it for every device.
The nvram partition parameters itself depend on the version of the
installed Apple iboot boot loader. m1n1 will fill in the current values
provided by Apple's iboot.
