sysfs: Use sysfs_attr_init and sysfs_bin_attr_init on dynamic attributes 

These are the non-static sysfs attributes that exist on
my test machine.  Fix them to use sysfs_attr_init or
sysfs_bin_attr_init as appropriate.   It simply requires
making a sysfs attribute present to see this.  So this
is a little bit tedious but otherwise not too bad.
