Add helper function to see if PMBus file exists

Due to some odd power supply behavior on some systems, certain PMBus
files in sysfs end up missing. Adding in a helper function to avoid
spurious tracing if an application so chooses to check for existence
before trying to read one of those files. See openbmc/openbmc#2364 issue
opened for this problem with the missing files.

Add hwmon support to PMBus class

Add support to allow the class to handle accessing
hwmon files even though the device path passed to
the constructor wasn't a hwmon path.

This is useful because the users of this class have
to access files in both locations.

For example:
PMBus p(basePath);

p.write("myfile", 1, Type::Base)
-> writes to basePath/myfile

p.write("myfile", 1, Type::Hwmon)
-> writes to basePath/hwmon/hwmonN/myfile
where hwmonN is the hwmon dir for the device

Add PMBus class

This class provides the interfaces to read PMBus devices
via sysfs files.

This commit provides 3 interfaces:
1) Write an integer (to provide: echo 1 > clear_faults)
2) Read a file that represents a bit in a register.
3) Read a file that represents a bit in a register within
a PMBus page (or in something that acts like a page).

Additional ones may be added in the future.

ReadFailure/WriteFailure exceptions will be thrown on errors.
