[PATCH v5 06/10] PCI: rockchip: fix missing phy manipulation for legacy phy

[Shawn Lin <shawn.lin@rock-chips.com>]

For instance, if a EP connect to lane3 and work under lagecy
phy mode, so struct phy phys[0..2] are all NULL. In this case,
rockchip->lanes_map & BIT(i) will tell the driver that lane0 is
already inactive, but what we want actually is to power off
the phys[0] for legacy phy mode. Fix this by add checking of
rockchip->legacy_phy for rockchip_pcie_deinit_phys.
