Subject: [PATCH 09/13] bus: auxiliary: increase AUXILIARY_NAME_SIZE

The auxiliary bus uses names in the form of "module_name.device_name"
for matching devices to drivers. Since the module name is the actual
module name, it can be quite long which doesn't leave enough room for
the device name.

This patch increases the size AUXILIARY_NAME_SIZE to 64 to allow for
both a ~32 character module name and a ~32 character device name.
