It doesn't seem to be used or required.

It causes kernel panic, though it is the right way to use bms and charger together

Unlike display panels, touchscreen can be upstreamed with the driver in Torvald's tree, so you might want to split it from the display panel commit.

is there an easy way to do it?

Not known yet, I assume. You need to do this during git rebase.

Do what, delete anyway?

Delete touchscreen parts, and commit with message blah blah

Revert commit, and reword the revert with message arm64: dts: qcom: msm8916-lenovo-phab: add touchscreen

Squash/fixup blah blah, and reword

You can probably reset the commit during the rebase, then split into two with git add --patch to only add some hunks (not sure if it would be split nicely though) and then squash the resulting touchscreen commit into the first one using another interactive rebase. Otherwise can probably interactive rebase -> edit first commit to add the TS and then fix the merge conflict when this commit applies.

You also need to fix it in msm8916-mainline/linux-panel-drivers#28 and generate the driver again.

can I use phab-panel?

Only when you have defined lenovo,phab-panel in lk2nd and it selects from multiple panels.
msm8916-mainline/lk2nd@933fbc3

Anyway here is the naming rule, <vendor>,[device-]<panel_name>.

<vendor>,[device-]<panel_name>.

I see panel_name, not panel-name

Basically it's meant to be dashes instead of underscores for compatible entries, if you know what I mean.

I'm not sure if you actually need both here... is "mains" required? and/or is there an example that uses mains that you have took this from? (I'd expect "mains" to mean "mains power" aka 220v or a barrel jack)

I don't think the dsi port schema has any gpios...
