Revert "arm64: dts: rockchip: add SPDIF audio to Beelink A1"

[ Upstream commit 03978cb ]

This reverts commit bdc4d38.

While Beelink A1 mostly follows the high-end RK3328 reference design,
it does not in fact have the S/PDIF connector, only HDMI and a 3.5mm
jack for the analog audio/TV codecs - the tiny form factor literally
doesn't have room to fit more!
