[PATCH v2 5/5] arm64: dts: exynos: gs101-oriole: add pd-disable and typec-power-opmode

[André Draszik]

When the serial console is enabled, we need to disable power delivery
since serial uses the SBU1/2 pins and appears to confuse the TCPCI,
resulting in endless interrupts.

For now, change the DT such that the serial console continues working.

Note1: We can not have both typec-power-opmode and
new-source-frs-typec-current active at the same time, as otherwise DT
binding checks complain.

Note2: When using a downstream DT, the Pixel boot-loader will modify
the DT accordingly before boot, but for this upstream DT it doesn't
know where to find the TCPCI node. The intention is for this commit to
be reverted once an updated Pixel boot-loader becomes available.
