commit 6ecb3f0b18b320320460a42e40d6fb603f6ded96 upstream.
Dell DW5829e same as DW5821e except CAT level. DW5821e supports CAT16 but DW5829e supports CAT9. There are 2 types product of DW5829e: normal and eSIM. So we will add 2 PID for DW5829e. And for each PID, it support MBIM or RMNET. Let's see test evidence as below:

BTW, the interface 0x6 of MBIM mode is GNSS port, which not same as NMEA port. So it's banned from serial option driver. The remaining interfaces 0x2-0x5 are: MODEM, MODEM, NMEA, DIAG.
