drivers: flash : introduce a new driver for the OCTOSPI This is the stm32 octospi driver based on the exisitng quadspi for stm32 devices and source code from the STM32Cube. This drivers initialized the peripheral and the NOR memory in SPI or OctoSPI mode with STR or DTR data Transfer rates. The NOR-flash can provide the SDFP table directly (if supported) or through the DeviceTree. Limitation: no DMA transfer. Signed-off-by: Francois Ramu <francois.ramu@st.com>

drivers: flash: Update drivers to use devicetree Kconfig symbol Update flash drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>
