arm64: dts: rockchip: Fix USB Type-C host mode for Radxa ROCK 5B+/5T

[ Upstream commit fbf90d1b697faf61bb8b3ed72be6a8ebeb09de3d ]

The Radxa ROCK 5B+/5T USB Type-C port supports Dual Role Data and
should also act as a host. However, currently, when acting as a host,
only self-powered devices work.

Since the ROCK 5B+ supports Dual Role Power, set the power-role
property to "dual" and the try-power-role property to "sink". (along
with related properties)

The ROCK 5T should only support the "source" power-role.

This allows the port to act as a host, supply power to the port, and
allow bus-powered devices to work.

Note that on the ROCK 5T, with this patch applied, it has been
observed that some bus-powered devices do not work correctly. Also,
it has been observed that after connecting a device (and the data-role
switches to host), connecting a host device does not switch the
data-role back to the device role. These issues should be addressed
separately.

Note that there is a separate known issue where USB 3.0 SuperSpeed
devices do not work when oriented in reverse. This issue should also be
addressed separately. (USB 2.0/1.1 devices work in both orientations)
