riscv: dts: spacemit: add 24c04 eeprom on Milk-V Jupiter

Browse Source 
The Milk-V Jupiter board includes a 24c04 eeprom on the i2c2 bus. The
eeprom contains an ONIE TLV table, which on the board I tested only
provides a product-name entry. Expose it via an onie,tlv-layout nvmem
layout.

The eeprom is marked as read-only since its contents are not supposed to
be modified.
