[PATCH 3/7] Staging: iio: adt7316: Add of_device_id table

[Shreeya Patel <shreeya.patel23498@gmail.com>]

When the kernel starts up, it kicks off compiled-in drivers
that match “compatible” entries it finds in the device tree.
At a later stage (when /lib/modules is available), all kernel modules
that match “compatible” entries in the device tree are loaded.
Hence to be able to use device tree for ADT7316, add of_device_id
table which specifies the supported devices through compatible
property.
Note that there is a fall back path in i2c that will result
in i2c_device_id table being used if there is no of_devcie_id table.
