oem-ibm : Add new filetype & logic for handling Progress Codes
- The intent behind this commit , is to add a new file type
for handling IBM Progress Codes.
- The Progress Codes are typically in bytes(<200 bytes), which
is why the host does an inband write rather than using the DMA.
- Once the Progress Code structure is received, pldm would peek into
the buffer to find out the Primary Code which is typically an 8 byte
Hex number (starts at a standard offset 40).
- Once , we get the Primary Code then we pack it into a structure and
set the dbus property which is hosted by the snoopd daemon.
