[RFC PATCH] riscv: dts: nezha-d1: Add memory

[Evan Green]

Add memory info for the D1 Nezha, which seems to be required for it to
boot with the stock firmware. Note that this hardcodes 1GB, which is
not technically correct as they also make models with different amounts
of RAM. Is the firmware supposed to populate this?
