core/pldm: Register PLDM as a blocklevel device
In the same way that ipmi-hiomap implements the PNOR access control
protocol, this patch allows to "virtualize" the content of a BMC flash
based on lid files.
Previously, flash PNOR partitions were viewed this way:
partitionXX=NAME, start address, end address, flags
The content of each partition is now stored in a lid file. In order to
continue to use the libflash library, we manually fill in the contents of
a fake flash header when accessing offset 0. This reproduces the behavior
via ipmi-hiomap of reading the flash header on the BMC.
For the reading and writing of BMC lids files, we convert the virtual
addresses of these 'fake' partitions by identifying: lid id.
