[PATCH v2] arm64: dts: qcom: monaco-evk: Enable primary USB controller in host mode

[Swati Agarwal]

Enable primary USB controller in host mode on monaco EVK Platform.

Primary USB controller is connected to a Genesys Logic USB HUB GL3590
having 4 ports. The ports of hub that are present on lemans EVK standalone
board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.

Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:

3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.

Primary USB Controller
          ↓
GL3590 USB Hub (4 ports)
    |
    |-- Port 1 → HD3SS3220 Type‑C Port Controller → USB‑C Connector
    |
    |-- Port 2 → Mezzanine USB Hub (when mezz attached)
    |
    |-- Port 3 → M.2 B‑Key Slot (when mezz attached)
    |
    |-- Port 4 → M.2 E‑Key Slot
                         (Default: BT via UART;
                          USB only if NFA765 module is installed)

Mark the primary USB controller as host only capable and add the HD3SS3220
Type-C port controller along with Type-c connector for controlling vbus
supply.

In hardware, DIP switches are present to select between USB0 and USB1 ports
for the primary Type‑C USB controller. By default, the switches are in
the OFF state, selecting the USB0 port. Add software support for both HS
and SS switches to eliminate the need for manually changing the DIP switch
position for USB1 operation. Add a USB1 hub reset pin to reset and activate
the hub after boot, ensuring proper detection from its pre‑boot inactive
state.

Changes in v2:
Split DT binding and DT patch.
Use gpio hog instead of pinctrl for usb hub reset and HS switch sel.
