phy: qcom: qmp-combo: Add SM8475 support

Has been tested with the following capabilities:
- USB Type-C at 10Gb/s
- DP Alt Mode, using HBR2
- USB Type-C at 480Mb/s + DP Alt Mode, using HBR2

RX and PCS USB tables had to be added, while serdes, TX and PCS tables were
reused from other SoCs.

Some SoCs such as SAR2130P, SM7550, SM7635 and SM8475 use 4nm-v1 PLLs.
For SM8475, trying to use qmp_v6_dp_serdes_tbl structs (which are for
4nm-v1.1 PLLs) causes link training to fail because of ref clock
differences, which in turn makes these structs differ.
Add structs for v1 PLLs as well.
