[RFC v3 05/13] ahci-platform: Pass ahci_host_priv ptr to ahci_platform_data init method

[Hans de Goede]

Some ahci_platform_data->init methods need access to the ahci_host_priv data.

Note:

When calling ahci_platform_data->init the ata_host has not been allocated yet,
so access to ahci_host_priv through the dev argument is not possible.

The hpriv->mmio argument may seem redundant, but it is useful for drivers
which live outside of drivers/ata and thus don't know the contents of the
ahci_platform_data data type.
