usb: phy: generic: Use proper helper for property detection

JIRA: https://issues.redhat.com/browse/RHEL-78837

commit 309005e
Author: Alexander Stein <alexander.stein@ew.tq-group.com>
Date: Mon, 20 Jan 2025 15:42:51 +0100

  Since commit c141ecc ("of: Warn when of_property_read_bool() is
  used on non-boolean properties") a warning is raised if this function
  is used for property detection. of_property_present() is the correct
  helper for this.
