There are a number of new changes at the ABI files that cause
them to produce warnings when generating ABI output.
Fix them.

This patch adds support for power management private feature under
FPGA Management Engine (FME). This private feature driver registers
a hwmon for power (power1_input), thresholds information, e.g.
(power1_max / crit / max_alarm / crit_alarm) and also read-only sysfs
interfaces for other power management information. For configuration,
user could write threshold values via above power1_max / crit sysfs
interface under hwmon too.

This patch adds support to thermal management private feature for DFL
FPGA Management Engine (FME). This private feature driver registers
a hwmon for thermal/temperature monitoring (hwmon temp1_input).
If hardware automatic throttling is supported by this hardware, then
driver also exposes sysfs interfaces under hwmon for thresholds
(temp1_max/ crit/ emergency), threshold alarms (temp1_max_alarm/
temp1_crit_alarm) and throttling policy (temp1_max_policy).

This patch adds support for global error reporting for FPGA
Management Engine (FME), it introduces sysfs interfaces to
report different error detected by the hardware, and allow
user to clear errors or inject error for testing purpose.

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.
