Enhance the Qualcomm Lemans EVK board file to support essential
peripherals and improve overall hardware capabilities, as
outlined below:
  - Enable GPI (Generic Peripheral Interface) DMA-0/1/2 and QUPv3-0/2
    controllers to facilitate DMA and peripheral communication.
  - Add support for PCIe-0/1, including required regulators and PHYs,
    to enable high-speed external device connectivity.
  - Integrate the TCA9534 I/O expander via I2C to provide 8 additional
    GPIO lines for extended I/O functionality.
  - Enable the USB0 controller in device mode to support USB peripheral
    operations.
  - Activate remoteproc subsystems for supported DSPs such as Audio DSP,
    Compute DSP-0/1 and Generic DSP-0/1, along with their corresponding
    firmware.
  - Configure nvmem-layout on the I2C EEPROM to store data for Ethernet
    and other consumers.
  - Enable the QCA8081 2.5G Ethernet PHY on port-0 and expose the
    Ethernet MAC address via nvmem for network configuration.
    It depends on CONFIG_QCA808X_PHY to use QCA8081 PHY.
  - Add support for the Iris video decoder, including the required
    firmware, to enable video decoding capabilities.
  - Enable SD-card slot on SDHC.

I think Mani has been asking lately to define these GPIOs inside the
port rather than in the host controller.
