2d910fe1e6 ata: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/ata/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

a7eb54d440 ata: libata: Make ata_platform_remove_one return void
The function returned zero unconditionally, so the function returning an
int is something between useless and irritating. With the goal to make
platform drivers' remove function return void, it's helpful to convert
the function accordingly. This converts several drivers to the new
.remove_new callback that was introduced to smoothen the platform driver
conversion.

17cc1ee6e8 ata: ahci_st: Fix compilation warning
If CONFIG_OF is disabled and the ahci_st driver is builtin (or
CONFIG_MODULES is disabled), then using the macro of_match_ptr()
results in the st_ahci_match variable being unused, which generates a
compilation warning and a compilation error if CONFIG_WERROR is enabled.

Fix this by directly assigning st_ahci_match to .of_match_table in the
st_ahci_driver platform driver definition.

3f74cd046f ata: libahci_platform: Parse ports-implemented property in resources getter
The ports-implemented property is mainly used on the OF-based platforms
with no ports mapping initialized by a bootloader/BIOS firmware. Seeing
the same of_property_read_u32()-based pattern has already been implemented
in the generic AHCI LLDD (glue) driver and in the Mediatek, St AHCI
drivers let's move the property read procedure to the generic
ahci_platform_get_resources() method. Thus we'll have the forced ports
mapping feature supported for each OF-based platform which requires that,
and stop re-implementing the same pattern in there a bit simplifying the
code.

e0e2674b92 ata: ahci_st: fixup layering violations / drvdata errors
Brian noticed while working on another SATA driver that uses libahci_platform,
an error in this driver; it tries to the the driver data for its
device, while libata also thinks it can set the driver data. See:

  ahci_platform_init_host()
  -> ata_host_alloc_pinfo()
     -> ata_host_alloc()
        -> dev_set_drvdata()

So instead of sticking the IP-specific platform data into drvdata, let's
use the plat_data variable that is reserved for this use.

Addtionally plat_data isn't set until ahci_platform_init_host() has been
called further down in probe(). So re-work the st_ahci_probe_resets and
st_ahci_deassert_resets functions to take ahci_host_priv *hpriv as a
parameter.

9a1e75e11a ahci: st: st_configure_oob must be called after IP is clocked.
Currently the ahci_st driver will hang the system on probe, as the
st_configure_oob function does some register writes before the IP
is clocked. This patch moves the function call to after
ahci_platform_enable_resources (which enables the IP clock), and
resolves the hang.

Addtionally st_ahci_configure_oob should be called in the st_ahci_resume
function, so we also rectify that ensuring it is also called after
the IP clock has been enabled.

018d5ef204 ata: ahci_platform: fix owner module reference mismatch for scsi host
The owner module reference of the ahci platform's scsi_host is
initialized to libahci_platform's one, because these drivers use a
scsi_host_template defined in libahci_platform.  So these drivers can
be unloaded even if the scsi device is being accessed.

This fixes it by pushing the scsi_host_template from libahci_platform
to all leaf drivers.  The scsi_host_template is passed through a new
argument of ahci_platform_init_host().

725c7b570f ata: libahci_platform: move port_map parameters into the AHCI structure
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.
