usb: typec: altmodes/displayport: Use proper macro for pin assignment check
While looking at the DP configuration VDO to determine the peripheral
configuration, the spec (Table 8-5: DisplayPort Configurations, VESA
DisplayPort Alt Mode Standard v2.0) lists the options as "UFP_U as a DP
Source/Sink Device".
So, use the correct macro while performing this check. Effectively it's
the same as the existing code, but the proposed macro describes the
state a little better.
No functional changes introduced.
