[PATCH 3/3] arm64: dts: qcom: sdm845-tama: Declare touchscreen as a panel follower

[Konrad Dybcio <konradybcio@kernel.org>]

From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>

Currently, the touchscreen relies on the idiosyncracies of Linux and
fw_devlink, wired up via a totally fake supply reference to keep the
driver probe order in check.

Resolve that properly by declaring the touchscreen as a panel follower
of the in-cell display panel.
