phy: qcom: edp: Add Nord PHY configuration data tables

This commit adds Nord-specific AUX channel, VCO divider, LDO and TX
resistor calibration data. These tables are sourced from HPG Tables
2-1-a, 2-1-b and 2-1-d.

[Severity: Low]
Does this code introduce unused static variables?

These arrays, as well as tx_res_cfg_nord below, are defined as static but are
not referenced anywhere in this commit. Defining unreferenced static arrays
triggers a -Wunused-const-variable compiler warning.

If the kernel is built with CONFIG_WERROR=y, this warning is promoted to an
error and breaks the build. While a later patch in this series (commit
1393c79f29bd788a83ce23c45373ba39e69132d0) references these tables,
intermediate patches must compile cleanly to maintain git bisectability.

[Severity: Low]
Does this code introduce an unused static function?

Similar to the static arrays above, qcom_edp_ldo_config_nord is defined as
static but never called in this commit. This triggers a -Wunused-function
warning, which will also break the build under CONFIG_WERROR=y.
