hwmon: (amc6821) add of_match table
[ Upstream commit 3f003fda98
]
Add of_match table for "ti,amc6821" compatible string.
This fixes automatic driver loading by userspace when using device-tree,
and if built as a module like major linux distributions do.
While devices probe just fine with i2c_device_id table, userspace can't
match the "ti,amc6821" compatible string from dt with the plain
"amc6821" device id. As a result, the kernel module can not be loaded.
