icside: don't use hwif->hwif_data
* Move ecard_set_drvdata() from icside_probe() to icside_register_v{5,6}(),
then use state->ioc_base instead of hwif->hwif_data in icside_maskproc()
and icside_dma_test_irq().
While at it:
* Add sel field to struct icside_state, then use state->{sel,ioc_base}
instead of ->{select,config}_data in icside_dma_setup().
There should be no functional changes caused by this patch.
