Use dev_dbg() instead of dev_err() in pcie_advk_check_pio_status().
For example CRS is not an error status, it just says that the request should be retried.
Without this, U-Boot spams the terminal with pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x100000 pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x108000 pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x110000 pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x120000 pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x128000 pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x130000 ... when a device is not connected to a PCIe switch (Unsupported Request from the switch).
