arm64: dts: mediatek: mt8195: Remove suspend-breaking reset from pcie0



[ Upstream commit 3374b5fb ]

When test suspend resume with 6.8 based kernel, system can't resume
and I got below error which can be also reproduced with 6.16 rc6+
kernel.

mtk-pcie-gen3 112f0000.pcie: PCIe link down, current LTSSM state: detect.quiet (0x0)
mtk-pcie-gen3 112f0000.pcie: PM: dpm_run_callback(): genpd_resume_noirq returns -110
mtk-pcie-gen3 112f0000.pcie: PM: failed to resume noirq: error -110

After investigation, looks pcie0 has the same problem as pcie1 as
decribed in commit 3d7fdd8e ("arm64: dts: mediatek: mt8195:
Remove suspend-breaking reset from pcie1").

Fixes: ecc0af6a ("arm64: dts: mt8195: Add pcie and pcie phy nodes")
