Subject: [PATCH] ata: xgene: Use of_device_get_match_data()

Use preferred of_device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

Signed-off-by: Rob Herring <robh@...nel.org>

Perhaps device_get_match_data() could be used here and all the ACPI
specific code dropped, but not sure if all the ACPI code is really
necessary.
