usb: typec: tipd: use min() to set tps6598x firmware packet size

Simplify the current firmware packet size check in the tps6598x
implementation by means of a single call to min(), which is what the
current code does in a more verbose, less elegant way.

This patch fixes a cocci warning ("WARNING opportunity for min()").
