arm64: dts: rockchip: Document unused device on i2c1

From: Chris Morgan <[email protected]>

Update the i2c1 bus noting that the unknown/unused device at 0x3c is an iSmartWare SW2001 "encryption IC".

Based on the documentation I was able to find, this IC appears to be used to authenticate a device for certain programs to ensure they only run on authorized devices as a form of digital rights management.
