external/common: Add POWERPC code reenable building pflash for POWER
As per commit to create the external/common code, this commit introduces
the POWER arch compatibility flash reading code.
This commit actually should cause no functional change to pflash (it won't
be able to access the BMC flash if it ever could), however rather than
accessing the flash via the debugfs opal_lpc_{read,write} interface it will
access it though the MTD interface provided by linux and importantly skiboot.
Not only does using the MTD interface allows applications to treat it like
flash despite the fact that they are talking through several layers of
abstraction. Using passing through skiboot means that all the access to the
flash from the Power8 can be protected from concurrent access.
