Subject: [PATCH 1/5] net: usb: qmi_wwan: add IDs for EM7565 (9X50) in "MBIM USBIF" config

This change was discovered and tested using author's own EM7565 device.

This "MBIM USBIF" configuration corresponds to the `AT!USBCOMP=1,1,xxx`
on-device USB composition setting. When activated, the VID:PID resets
to 1199:90b1 ("application" mode) + 1199:90b0 ("boot" mode, i.e. QDL).

The "MBIM USBIF" label comes from on-device help:

---8<---
AT!USBCOMP=?
!USBCOMP:
AT!USBCOMP=<Config Index>,<Config Type>,<Interface bitmask>
  <Config Index>      - configuration index to which the composition applies, should be 1

  <Config Type>       - 1:MBIM USBIF, 2:PCIE USBIF, 3:Legacy-Generic, 4:RNDIS

  <Interface bitmask> - DIAG     - 0x00000001,
                        NMEA     - 0x00000004,
                        MODEM    - 0x00000008,
                        RMNET0   - 0x00000100,
                        MBIM     - 0x00001000,
  e.g.
  10D  - diag, nmea, modem, rmnet interfaces enabled
  1009 - diag, modem, mbim interfaces enabled

  The default configuration is:
  at!usbcomp=1,3,10F

OK
