spi: spi-qpic-snand: handle 'use_ecc' parameter of qcom_spi_config_cw_read()

During raw read, neither the status of the ECC correction nor the erased
state of the codeword gets checked by the qcom_spi_read_cw_raw() function,
so in case of raw access reading the corresponding registers via DMA is
superfluous.

Extend the qcom_spi_config_cw_read() function to evaluate the existing
(but actually unused) 'use_ecc' parameter, and configure reading only
the flash status register when ECC is not used.

With the change, the code gets in line with the corresponding part of
the config_nand_cw_read() function in the qcom_nandc driver.
