mips: octeon: Add cvmx-sriox-defs.h header file

Import cvmx-sriox-defs.h header file from 2013 U-Boot. It will be used
by the later added drivers to support PCIe and networking on the MIPS
Octeon II / III platforms.

+ * can be read regardless of whether the SRIO is selected or being reset.  Although some other
+ * registers can be accessed while the ACCESS bit is zero (see individual registers for details),
+ * the majority of SRIO registers and all the SRIOMAINT registers can be used only when the
+ * ACCESS bit is asserted.
+ *
+ * This register is reset by the coprocessor-clock reset.
