-After applying the following changes I could verify functionality by
-mounting a filesystem on the cfdisk and reading/writing files in it.
-
-The set_irq_type() function must be wrong, as there is no set_type()
-function defined for the rb532 IRQ chip. But as the used IRQ actually is
-being triggered by a GPIO, setting it's interrupt level should be the
-right alternative. Also to clear a GPIO triggered IRQ, the source has to
-be cleared. This is being done at the end of rb532_pata_irq_handler.

-Originally this must have been a rewrite error when introducing
-'chain_index'. But the original driver did not use the previous chain

-Also this is not an "index" but rather the penultimate element in the
