Currently the driver uses host->iomap to store all the iomapped BARs

window).

We're going to teach AHCI to work with non-PCI buses, so there are two
options to make this work:

1. "fake" host->iomap array for non-PCI devices, and place the needed
address at iomap[AHCI_PCI_BAR];
2. Get rid of host->iomap usage, instead introduce a private mmio
field.

This patch implements the second option.

Does platform code not contain any devres support?

At a minimum, you should be using devm_ioremap(), yes?

Nevermind, I see this now in the platform driver.
