[PATCH v2 16/17] riscv: dts: spacemit: k3-com260-ifx: enable the DisplayPort output

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

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

CoM260-IFX carries a single DisplayPort output, so the second DPU and
the DisplayPort controller it feeds are enabled.

v2:
- describe the DP receptacle (dp-connector) and link it to dp1 port@1
