QSPI test should use defined QSPI pins

Example:

        "NUCLEO_L4R5ZI": {
            "target.device_has_add": ["QSPI"],
            "target.components": ["QSPIF"],
            "drivers.qspi_io0": "PE_12",
            "drivers.qspi_io1": "PB_0",
            "drivers.qspi_io2": "PE_14",
            "drivers.qspi_io3": "PE_15",
            "drivers.qspi_sck": "PB_10",
            "drivers.qspi_csn": "PA_2",
            "target.macros_add": ["QSPI_FLASH_CHIP=MX25R6435F"],
            "qspif.QSPI_FREQ": "8000000"
        },
