[ Upstream commit c577f4a5a08bb9677e12ddafb62e2f3a901de87f ]
Currently the bitwise operations on the u16 variable 'status' with
the setting ROCKCHIP_PCIE_EP_CMD_STATUS_IS are incorrect because
ROCKCHIP_PCIE_EP_CMD_STATUS_IS is 1UL<<19 which is wider than the
u16 variable.
Fix this by making status a u32.
Fixes: cf590b078391 ("PCI: rockchip: Add EP driver for Rockchip PCIe controller")
