[PATCH v2] ata: libahci: Silence compiler warning on 64-bit

[Thierry Reding]

From: Thierry Reding <treding@xxxxxxxxxx>

Commit 725c7b570fda (ata: libahci_platform: move port_map parameters
into the AHCI structure) moves flags into the struct ahci_host_priv's
.flags field, which causes compiler warnings on 64-bit builds when that
value is cast to a void * pointer. Cast to an unsigned long so that the
subsequent cast to a pointer doesn't produce a warning.

Signed-off-by: Thierry Reding <treding@xxxxxxxxxx>

Changes in v2:
- cast unsigned int to unsigned long to avoid the compiler warning and
  keep the flags field's type as-is
