soc/intel/alderlake: mb/intel/sm: Add tcss code
Enable FSP 'MultiPhaseSilicon' init to execute tcss configure during silicon init. Type-c aux lines DC bias changes are propagated from tigerlake platform. TEST=Verified superspeed pendrive detection on coldboot.

- * IOM Port Config
- * If a port orientation needs to be controlled by the SOC this setting must be
- * updated to reflect the correct GPIOs being used for the SOC port flipping.
- * There are 4 ports each with a pair of GPIOs for Pull Up and Pull Down
- * 0,1 are pull up and pull down for port 0
- * 2,3 are pull up and pull down for port 1
- * 4,5 are pull up and pull down for port 2
- * 6,7 are pull up and pull down for port 3
- * values to be programmed correspond to the GPIO family and offsets
+ * These GPIOs will be programmed by the IOM to handle biasing of the
+ * Type-C aux (SBU) signals when certain alternate modes are used.
+ * `pad_auxn_dc` should be assigned to the GPIO pad providing negative
+ * bias (name usually contains `AUXN_DC` or `AUX_N`); similarly,
+ * `pad_auxp_dc` should be assigned to the GPIO providing positive bias
+ * (name often contains `AUXP_DC` or `_AUX_P`).
