usb: typec: pd: Remove usb_suspend_supported sysfs from sink PDO

commit e4e7b2dc27c4bb877d850eaff69d41410b2f4237 upstream.

As per USB PD specification, 28th bit of fixed supply sink PDO
represents "higher capability" attribute and not "usb suspend
supported" attribute. So, this patch removes the usb_suspend_supported
attribute from sink PDO.
