crypto: atmel-{aes,sha,tdes} - Retire crypto_platform_data
These drivers no longer need it as they are only probed via DT. crypto_platform_data was allocated but unused, so remove it. This is a follow up for: commitalistair/sensors45a536e3a7("crypto: atmel-tdes - Retire dma_request_slave_channel_compat()") commitdb28512f48("crypto: atmel-sha - Retire dma_request_slave_channel_compat()") commit62f72cbdcf("crypto: atmel-aes - Retire dma_request_slave_channel_compat()") Signed-off-by: Tudor Ambarus <tudor.ambarus@microchip.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
