This series enables PCIe for the Eliza EVK board (CQS SoM on EVK carrier). The Eliza EVK exposes two PCIe ports: - PCIe0 drives an M.2 E key connector. The 3.3V supply is GPIO-controlled via a TCA9538 I/O expander on I2C4. The slot hosts a WLAN module (connected over PCIe) and a Bluetooth device (connected over UART5), modelled with the pcie-m2-e-connector binding. - PCIe1 (8GT/s x2) connects to a Toshiba TC9563 PCIe switch, whose management interface sits on I2C4 (address 0x77). The TC9563 RESX# and PERST# lines are OR-ed internally; reset is driven via a TLMM GPIO on the RESX# pin. The iommu-map covers all downstream switch ports (SID range 0x1400-0x1408). The M.2 WLAN module carries a Qualcomm QCC2072 Bluetooth chip. A device-ID entry is added to the M.2 power sequencer so the serdev node for the BT UART interface is created on PCI enumeration.
