A platform_driver does not need to set an owner, it will be populated by the
driver core.

This patch moves force_port_map and mask_port_map into the
ahci_host_priv structure. This allows to modify them into the AHCI
framework. This is needed by the new dt bindings representing ports as
the port_map mask is computed automatically.

Parameters modifying force_port_map, mask_port_map and flags have been
removed from the ahci_platform_init_host() function, and inputs in the
ahci_host_priv structure are now directly filed.

Make of_device_id array const, because all OF functions handle it as const.

Add a dynamic host_flags argument to make ahci_platform_init_host more flexible,
then remove the AHCI_HFLAGS(...) argument from some driver's ata_port_info,
and pass that in as the new argument.

struct ahci_platform_data is deprecated (please see comments in
<linux/ahci_platform.h> for details).  Convert ahci_st driver to
use custom ->host_stop method instead.

* The config option for ahci_st driver was renamed from
  CONFIG_SATA_AHCI_ST to CONFIG_AHCI_ST but Makefile was
  not updated.  Fix it (also while at it move the ahci_st
  driver entry below ahci_imx and ahci_sunxi ones).

* Fix a few build issues in the ahci_st driver itself.

This is where we disable IRQs on suspend and update the internal

ata_platform_remove_one() allows us to specify our own exit function
via platform data then goes off and removes ATA Host and Port in
preparation for device removal.

Other devices have adopted similar naming conventions which have been
accepted as the standard. This patch brings any mention of the the ST
AHCI driver into line with them.
