From: Thor Thayer <tthayer@opensource.altera.com>

In preparation for additional memory module ECCs, the IRQ and
check_deps() functions are being made available to all the
memory buffers. Move it outside of the OCRAM only area.

Signed-off-by: Thor Thayer <tthayer@opensource.altera.com>

v2  New patch. Move shared functions outside OCRAM only area.
