Handle OCC EAGAIN & EREMOTEIO in 4.13
This is a temporary fix until the following issues are completed:
openbmc/openbmc#2327
openbmc/openbmc#2329
When an EAGAIN or an EREMOTEIO return code is received by hwmon
from the OCC driver in the 4.13 kernel, they should be translated to
an unavailable sensor(0x00) and failed sensor(0xFF) scaled values
respectively. This will keep the OCC hwmon instance running and allow
applications to continue using these sensors as they were reported under
the mainline openbmc/linux 4.10 kernel.
Tested:
Verified return codes are caught and sensor value modified

Exposes generic hwmon entries as DBus objects.
To build this package, do the following steps:
1. ./bootstrap.sh
2. ./configure ${CONFIGURE_FLAGS}
3. make
To full clean the repository again run `./bootstrap.sh clean`.
To enable the use of Linux features like cgroups prioritization and udev/systemd control, one instance of phosphor-hwmon is intended to be run per hwmon sysfs class instance. This requires an algorithm for selecting a stable, well-known D-Bus busname. The algorithm is <PREFIX>-<ID>.Hwmon<N> where PREFIX is an autoconf configurable prefix (BUSNAME_PREFIX, xyz.openbmc_project by default), ID is a std::hash of the /sys/devices path backing the hwmon class instance, and N is the implemented phosphor-hwmon D-Bus API version.
