[PATCH 12/32] plat-orion: introduce ORION_ADDR_MAP_NO_REMAP

[Thomas Petazzoni]

Currently, the addr_map_info structure uses an "int remap" to allow
SoC-specific code to specify whether a given address decoding window
should be remapped, and if so, the remapping address. To do so, it
tests if the int is less than zero (no remap) or greater than
zero. Unfortunately, this prevents any remapping address that is
higher than 2 GB.

As a first step to fix this, we introduce ORION_ADDR_MAP_NO_REMAP
define, that will be the "remap" value that SoC-specific code should
pass to not have a remapping.
