gcc_lpass_trig_clk is not used downstream, therefore there is no reason to
expect it to be needed for clients. Let's remove it because messing with
the clock has been observed to cause Linux hangs when the qdss_clk is
initialized by rpmcc.

Sorry. Used to other maintainers.
From your v1 comment, would be
Fixes: 4807c71cc688 (arm64: dts: Add msm8998 SoC and MTP board support)
I'm assuming from the above, you'll just apply the tag when you apply
the change.

Hmm I already marked it as 'changes requested' but OK, I can pick it up
and add the fixes tag now.
