vc/amd/opensil: introduce common mpio/chip.h header file

The chip drivers in the devicetree use the path where the corresponding
chip.h file resides both to include this chip.h file in the static.c
generated by util/sconfig from the devicetree and also for the names of
the chip config and chip ops struct. To be able to build a SoC using
either the MPIO chip driver from the openSIL stub or from the actual
openSIL glue code without needing different devicetree files for the
different cases, introduce a common MPIO chip.h file that then includes
the correct MPIO header file. The chip config and ops structures also
need to be renamed to take this change into account.

Thanks to Matt for pointing out how to make the path to the actual MPIO
chip.h file configurable via a Kconfig setting. This allows overriding
this path from site-local without the need to have any reference to
site-local in the upstream code.
