Subject: [PATCH v2] staging: greybus: Constify static struct kobj_type
 gb_audio_module_type

Constify static struct kobj_type gb_audio_module_type to prevent
modification of data shared across many instances, ensuring that the
structure's usage is consistent and predictable throughout the driver
and allows the compiler to place it in read-only memory.
