bus: mhi: host: pci_generic: Add Foxconn T99W696 modem

Browse Source 
T99W696 modem is based on Qualcomm SDX61 chipset, which is an economic
version compared to the baseline SDX62/SDX65 chipsets. Add support for it
by introducing a new 'mhi_channel_config'. Since this modem supports the
NMEA channel, a new config is needed.
