[PATCH v2 15/17] riscv: dts: spacemit: k3-pico-itx: enable the DisplayPort output

[Cody Kang via B4 Relay <devnull+codykang.hk.gmail.com@kernel.org>]

From: Cody Kang <codykang.hk@gmail.com>

Pico-ITX brings the second DPU's output to an external DisplayPort
connector. Enable that DPU and the DisplayPort controller it feeds.
