drivers/spi/spi_flash: explicitly handle STMicro deep power state
In order to provide more consistent probing in future refactorings, pull out the release from deep sleep path in STMicro's SPI flash probing function. Call that function explicitly when RDID doesn't return anything at all. The old STMicro parts, even if supporting RDID, won't decode that instruction while in a deep power down state. Instead of re-issuing RDID after the successful wake assume the id fixup is valid.
