[PATCH v7 3/3] arm64: dts: qcom: eliza-evk: Add PCIe1 with TC9563 PCIe switch

[Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com>]

The Eliza EVK board connects PCIe1 (8GT/s x2) to a Toshiba TC9563
PCIe switch. Enable PCIe1 and its QMP PHY nodes.

TC9563 uses I2C (at address 0x77 on I2C4) for its management interface.

Override the base iommu-map with the expanded set covering all the
switch's downstream ports (0x1400-0x1408 SID range).

The TC9563 RESX# and PERST# are OR-ed internally to assert reset on the
switch. Use TC9563 RESX# pin via a TLMM GPIO and skip wiring PERST#
from the PCIe controller.
