arm64: dts: mediatek: mt8195: Remove suspend-breaking reset from pcie1
The MAC reset for PCIe port 1 on MT8195 when asserted during suspend
causes the system to hang during resume with the following error (with
no_console_suspend enabled):
mtk-pcie-gen3 112f8000.pcie: PCIe link down, current LTSSM state: detect.quiet (0x0)
mtk-pcie-gen3 112f8000.pcie: PM: dpm_run_callback(): genpd_resume_noirq+0x0/0x24 returns -110
mtk-pcie-gen3 112f8000.pcie: PM: failed to resume noirq: error -110
This issue is specific to MT8195. On MT8192 with the PCIe reset,
MT8192_INFRA_RST4_PCIE_TOP_SWRST, added to the DT node, the issue is not
observed.
Since without the reset, the PCIe controller and WiFi card connected to
it, work just as well, remove the reset to allow the system to suspend
and resume properly.
