Subject: [PATCH 1/1] ssb: use DEVICE_ATTR_ADMIN_RW macro

Use DEVICE_ATTR_ADMIN_RW macro helper instead of plain DEVICE_ATTR, which
makes the code a bit shorter and easier to read.

It normalizes the name of the hook function for read and write operations
of the property file, so it's also easier to associate and find.
