[PATCH] PCI: rockchip: fix bitwise operations on status and ROCKCHIP_PCIE_EP_CMD_STATUS_IS

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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.  (Not tested).

Fixes: cf590b078391 ("PCI: rockchip: Add EP driver for Rockchip PCIe controller")
