sunxi64: enable USB_SERIAL_OPTION (module) for GSM/UMTS/LTE modem support (#10050)

* sunxi64: enable USB_SERIAL_OPTION (module) for GSM/UMTS/LTE modem support

Enable additional USB serial modem drivers for sunxi64 current kernel configuration.

This patch enables the following USB serial drivers as modules:

- CONFIG_USB_SERIAL_IPW=m
- CONFIG_USB_SERIAL_QUALCOMM=m
- CONFIG_USB_SERIAL_OPTION=m

These drivers are commonly required for USB WWAN/LTE/3G/4G modems using the USB serial/option interface, including devices from vendors such as D-Link, Huawei, Quectel, SIMCom, and similar chipsets.

Enabling these drivers improves out-of-the-box support for USB cellular modems without requiring manual kernel reconfiguration.

No functional change for existing USB stack; only enables additional optional modem drivers as modules.

* sunxi64: enable USB_SERIAL_OPTION (+IPW, QUALCOMM) for edge too

Addresses review "Edge still missing": the modem USB-serial drivers were added
to current but not edge. Add USB_SERIAL_IPW/QUALCOMM/OPTION (=m) to the edge
config so the edge USB_SERIAL block matches current. Legacy already carries
them (and the full usb-serial set), so it is unchanged.
