hwmon: (pmbus/adm1275) Support module auto-loading

Browse Source 
Populating the i2c_device_id -table is not enough to make the
driver module automatically load when device-tree node for the
power-monitor is parsed at boot.

Adding the of_device_id tables causes the driver module to be
automatically load at boot. Testing has been done with rather old Debian
system.

When inspecting the generated module-aliases with the insmod, following
entries seem to be the difference:

alias:          of:N*T*Cadi,adm1075C*
alias:          of:N*T*Cadi,adm1075

I suspect these are required for the module loading to work.
