[platforms: PATCH 3/9] Marvell/Armada70x0Db: Enable device tree support

[Marcin Wojtas <mw@semihalf.com>]

This patch enables compilation of the Armada 7040 DB
device tree. Necessary adjustments are added, so that
the OS can use efi-rtc and has no access to the SPI
flash

Contributed-under: TianoCore Contribution Agreement 1.1
