fpga: dfl: fme: add header sub feature support
The Header Register set is always present for FPGA Management Engine (FME),
this patch implements init and uinit function for header sub feature and
introduces several read-only sysfs interfaces for the capability and
status.
Sysfs interfaces:
* /sys/class/fpga_region/<regionX>/<dfl-fme.x>/ports_num
Read-only. Number of ports implemented
* /sys/class/fpga_region/<regionX>/<dfl-fme.x>/bitstream_id
Read-only. Bitstream (static FPGA region) identifier number. It contains
the detailed version and other information of this static FPGA region.
* /sys/class/fpga_region/<regionX>/<dfl-fme.x>/bitstream_metadata
Read-only. Bitstream (static FPGA region) meta data. It contains the
synthesis date, seed and other information of this static FPGA region.
