hwmon: (ad7418) Use permission specific SENSOR[_DEVICE]_ATTR variants
Use SENSOR[_DEVICE]_ATTR[_2]_{RO,RW,WO} to simplify the source code, to improve readbility, and to reduce the chance of inconsistencies. Also replace any remaining S_<PERMS> in the driver with octal values. The conversion was done automatically with coccinelle. The semantic patches and the scripts used to generate this commit log are available at https://github.com/groeck/coccinelle-patches/hwmon/. This patch does not introduce functional changes. It was verified by compiling the old and new files and comparing text and data sizes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
