hwmon: (smsc47m1) Mark driver struct with __refdata to prevent section mismatch

Browse Source 
As described in the added code comment, a reference to .exit.text is ok
for drivers registered via module_platform_driver_probe(). Make this
explicit to prevent the following section mismatch warning

	WARNING: modpost: drivers/hwmon/smsc47m1: section mismatch in reference: smsc47m1_driver+0x8 (section: .data) -> smsc47m1_remove (section: .exit.text)

that triggers on an allmodconfig W=1 build.
