arm64: dts: rockchip: fix second M.2 slot on ROCK 5T

Browse Source 
The Radxa ROCK 5T has two M.2 slots, much like the Radxa Rock 5B+. As it
stands, the board won't be able to use PCIe3 if the second M.2 slot is
in use.

Fix this by adding the necessary node enablement and data-lanes property
to the ROCK 5T device tree, mirroring what's in the ROCK 5B+ device
tree.
