Subject: PCI: rockchip: Fix negotiated lanes calculation

From: Shawn Lin <[email protected]>

commit 45e9320f3a4ef9588ee50a2eb1891c4bfdbb07df upstream.

The calculation of negotiated lanes is wrong: it should be shifted by PCIE_CORE_PL_CONF_LANE_SHIFT, but it is shifted by PCIE_CORE_PL_CONF_LANE_MASK instead. Let's fix it.
