Currently, in stm32_qspi_claim_bus(), QSPI_CR and QSPI_DCR registers are saved in stm32_ospi_flash struct on first flash memory initialization and restored on each flash accesses.As the logic of spi-uclass.c changed since 'commit 741280e9accd ("spi: spi-uclass: Fix spi_claim_bus() speed/mode setup logic")' set_speed() and set_mode() callbacks are called systematically when bus speed or bus mode need to be updated, QSPI_CR and QSPI_DCR registers are set accordingly. So stm32_qspi_claim_bus() can be updated by removing QSPI_CR and QSPI_DCR save/restore code and struct stm32_ospi_flash can be removed as well.
