Update the WWAN/BB antenna to use the Antenova SR4L034-R antenna

Placment and routing of level shifters U1801 and 1802.

Detected a confict between local net labels and hierarchical net labels
which resulted in level shifter U1801 completely bridged.

Renamed labels in schematic.

Placed and wired auxiliary components (e. g. levelshifter) around mPCIE modem.

Route USB2 to the hub chip's upstream port and re-order & route each of the downstream ports to their respective locations (smartcard, mPCIe, & M.2), place and route the HDMI fuse, schottky diodes, TVS diodes, capacitors, and pull-up resistors, route the rest of the HDMI's interface to the SoM (HPD & I2C), adjust the GNSS antenna's CPW width using the PCB manufacturer's recommendation from their calculations

The HDMI circuit should be complete now. The GNSS & WiFi+BT antennae should also be complete. The GNSS module's RX & TX lines need to be routed next.

Add ANT-LTE-CER-T as the baseband modem antenna into the schematic and BoM, update the layout accordingly

Connected audio path modem card -> SOM (4 PCM signals).

Placment and routing of glue logic for miniPCIE modem card.
