pnor_partition_table: Raise exception for unmapped offsets

Allow reads and writes of offsets that don't map onto partitions defined
in the ToC. Do so by ignoring the mapping failure and filling a window
with 0xff in the hole from the requested offset to the following
partition.

This change also removes the reliance on InternalFailure as the
exception of choice for communicating failures. We can do better without
the teeth-pulling required by phosphor-logging by translating custom
exceptions into phosphor-logging exceptions at the edges.
