spi_flash: Make a deep copy of spi_slave structure

Commit 36b81af (spi: Pass pointer to spi_slave structure in
    spi_setup_slave) changes the way spi_setup_slave handles the spi_slave
    structure. Instead of expecting spi controller drivers to maintain
    spi_slave structure in CAR_GLOBAL/data section, caller is expected to
    manage the spi_slave structure. This requires that spi_flash drivers
    maintain spi_slave structure and flash probe function needs to make a
    copy of the passed in spi_slave structure.

This change fixes the regression on Lenovo X230 and other mainboards.
