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.
