hwmon: (s3c-hwmon) Fix build error

The previous patch, commit 1edd828d8b4b0d06e9171027a2d9c1eb634c1339 was
from the wrong tree and thus broke the current build which had the
channel configuration name changed.

Fix the following build errors:

drivers/hwmon/s3c-hwmon.c: In function 's3c_hwmon_probe':
drivers/hwmon/s3c-hwmon.c:326: warning: initialization from incompatible pointer type
drivers/hwmon/s3c-hwmon.c:331: error: dereferencing pointer to incomplete type
drivers/hwmon/s3c-hwmon.c:336: error: dereferencing pointer to incomplete type
