Subject: [PATCH 2/6] arm64: dts: rockchip: rock960: Add on-board LED support

Add on-board LED support for Rock960 board based on the following
standard used by rest of the 96Boards:

device-name:green:user1  default-trigger: heartbeat
device-name:green:user2  default-trigger: mmc0/disk-activity
                                          (onboard-storage)
device-name:green:user3  default-trigger: mmc1 (SD-card)
device-name:green:user4  default-trigger: none, panic-indicator
device-name:yellow:wlan  default-trigger: phy0tx
device-name:blue:bt      default-trigger: hci0-power
