icside: don't use hwif->hwif_data

Browse source 
* 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.
