cbfs: support concurrent media channels properly
Coreboot generic CBFS media API does not support
multiple media access instances, but it should.
With this fix the CBFS context (memory cache for
SPI accesses) is shared among all open media access
streams. A better memory management scheme might be
required, but for now this fix allows to support
booting deptcharge and accessing VPD through two
independent CBFS media streams.
BUG=chrome-os-partner:32152
TEST=no exception is thrown when the second stream
is opened
