Adding p9a_get/put_mmio and explorer_inband

p9a_get/put_mmio implements getMMIO and putMMIO via
the ADU.

explorer_inband implements functions to access MSCC
MMIO registers, MSCC RAM space for commands and
responses, and IBM scom registers via inband/mmio
to Explorer.

+  <description>
+       OMI inband BAR address offset.
+
+       Set by platform.
+
+       One Axone bar register is set per MC channel for MMIO and another
+       is set per MC channel for config space. The bar is shared between
+       both sub-channels each with an OCMB.  The upper bit of the bar
+       size is used to determine which sub-channel is selected.  This
+       means that for two OCMB's their config space is contiguous and
+       their MMIO space is contiguous.  Therefore a single OCMB's MMIO
+       and config space cannot be contiguous.  However, we can still
+       use one BAR attribute.  The p9a_omi_setup_bars procedure can interleave
+       the config space and MMIO space as shown in the table bellow.
+       For example, both MMIO and config bar sizes are 2GB.  The 2GB
+       bit becomes the selector for the subchannel.  The 4GB bit becomes
+       the offset applied for MMIO operations.
+
+
+       Each OCMB is assigned one base address attribute.
