sysfs: introduce callback attribute_group::bin_size
Several drivers need to dynamically calculate the size of an binary
attribute. Currently this is done by assigning attr->size from the
is_bin_visible() callback.
This has drawbacks:
* It is not documented.
* A single attribute can be instantiated multiple times, overwriting the
shared size field.
* It prevents the structure to be moved to read-only memory.
Introduce a new dedicated callback to calculate the size of the
attribute.
