driver core: Introduce device_create_groups
commit 39ef311204941ddd01ea2950d6220c8ccc710d15 upstream.
device_create_groups lets callers create devices as well as associated
sysfs attributes with a single call. This avoids race conditions seen
if sysfs attributes on new devices are created later.
[fixed up comment block placement and add checks for printk buffer
formats - gregkh]
