Subject: [PATCH v2 1/7] arm64: dts: rockchip: ficus: Add on-board LED support

Add on-board LED support for Ficus board based on the following
standard used by other 96Boards:

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