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.

+/// @file exp_inband.H
+/// @brief Explorer specifics for get/putMMIO inband ops
+///
+/// One Axone bar register is set per MC channel for MMIO, and another
+/// is set per MC channel for config space. Each bar is shared between
+/// both sub-channels each with an OCMB. The upper bit of the address
+/// determined by the bar sizes is used to determine which sub-channel
+/// is selected. This means that for a pair of OCMB's on a channel
+/// 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 and the set_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. For example:
+/// ocmb | BAR ATTRIBUTE | Type | Base reg - end addr | size | sub-ch
+/// +-----+--------------------+------+-----------------------------------------+------+-------
+/// ocmb0 | 0x0006030200000000 | cnfg | 0x0006030200000000 - 0x000603027FFFFFFF | 2GB | 0

+/// Bit 33 of the 64 bit address in big endian order determines if
+/// the MMIO operation is a SCOM to the core or a register access
+/// to MSCC space. If an MSCC access falls within the range specified
+/// by the MSCCRNGE core register it is an access to the MIPS SRAM.
+/// Specific locations within the SRAM have been set asside for command
+/// and response buffers. Once written an interrupt must be issued
+/// to MIPS indicating a new command is ready. Responses will send
+/// an interrupt back to the host.
