phy: rockchip-typec: Fix unsigned comparison with less than zero

[ Upstream commit 7110c2fa9ed6f864986b26321f96be39dbfb1757 ]

The dp and ufp are defined as bool type, the return value type of
function extcon_get_state should be int, so the type of dp and ufp
are modified to int.

./drivers/phy/rockchip/phy-rockchip-typec.c:827:12-14: WARNING: Unsigned expression compared with zero: dp > 0.
