drivers/spi/spi_flash: assume spi_flash read callback exists
spi_flash_erase() and spi_flash_write() already assume their respective callbacks are supplied in the spi_flash_ops object. Make the same assumption in spi_flash_read(). In order to do this the spi_flash_ops objects from the drivers need to reference the the previously used fallback read command, spi_flash_read_chunked(). This function is made global and renamed to spi_flash_cmd_read() for consistency. By doing this further dead code elimination can be achieved when the spi flash drivers aren't included in the build. A Hatch Chrome OS build achieves a further text segment reduction of 0.5KiB in verstage, romstage, and ramstage.
