drivers: flash: stm32 ospi can read the SFDP table from the DTS

When the SFDP table is provided by the DeviceTree with sfdp-bfp property
It is NOT read from the octoFlash.
If no table exists in the DTS and flash read SPDP fails,
the device init fails.
Availability of this sfdp_read API is conditional
on selecting CONFIG_FLASH_JESD216_API.
