b37260bca1 phy: rockchip: naneng-combphy: Use signal from comb PHY on RK3588
Route signal from comb PHY instead of PCIe3 PHY to PCIe1l0 and PCIe1l1.

d49dc884cb phy: rockchip: naneng-combphy: Add support for multiple resets
Some variants of the PHY have more than just one reset.
To cover all cases, request the rests in bulk rather than just
the reset at index 0.
