====================
Armada 7k/8k PP2 ACPI support

I quickly resend the series, thanks to Antoine Tenart's remark,
who spotted !CONFIG_ACPI compilation issue after introducing
the new fwnode_irq_get() routine. Please see the details in the changelog
below and the 3/7 commit log.

mvpp2 driver can work with the ACPI representation, as exposed
on a public branch:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/marvell-armada-wip
It was compiled together with the most recent Tianocore EDK2 revision.
Please refer to the firmware build instruction on MacchiatoBin board:
http://wiki.macchiatobin.net/tiki-index.php?page=Build+from+source+-+UEFI+EDK+II

ACPI representation of PP2 controllers (withouth PHY support) can
be viewed in the github:
* MacchiatoBin:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/blob/71ae395da1661374b0f07d1602afb1eee56e9794/Platforms/Marvell/Armada/AcpiTables/Armada80x0McBin/Dsdt.asl#L201

* Armada 7040 DB:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/blob/71ae395da1661374b0f07d1602afb1eee56e9794/Platforms/Marvell/Armada/AcpiTables/Armada70x0/Dsdt.asl#L131

I will appreciate any comments or remarks.

Best regards,
Marcin
