[PATCH 06/26] x86 STA2X11: select devicetree related config items.

[Davide Ciminaghi]

This patch selects some config items needed for adding device tree support
to STA2X11 based machines. In particular:

* OF_DYNAMIC is needed to use of_detach_node() and avoid instantiating
  the same node twice.

* IRQ_DOMAIN is needed because irq_of_parse_and_map() needs
  irq_create_of_mapping(), which is part of the irqdomain stuff.
