pkg/driver_atwinc15x0: don't use SPI Flash driver

Browse Source 
The only function of the SPI flash driver part that is called by other parts of the package is `spi_enable_flash(0)` to disable the SPI flash during driver deinitialisation for power consumption reasons. Since we are not deinitialising the driver, the function is not called and can be commented out to compile the package without the SPI flash driver part.

Subject: [PATCH 12/12] nmdrv: don't call spi_enable_flash(0)
SPI Flash isn't used in RIOT. Disabling the SPI Flash with `spi_enable_flash(0)` is the only function call to the SPI Flash driver. Therefore we don't use the SPI Flash driver at all and comment out this call to prevent an undefined reference.
