[PATCH] drivers/base/firmware_class.c: cleanups

- remove the following global function that is both unused and
  unimplemented:
  - register_firmware()

- make the following needlessly global function static:
  - firmware_class_uevent()

    on the setup, so I think that the choice on what firmware to make
    persistent should be left to userspace.
 
- - Why register_firmware()+__init can be useful:
-        - For boot devices needing firmware.
-        - To make the transition easier:
-                The firmware can be declared __init and register_firmware()
-                called on module_init. Then the firmware is warranted to be
-                there even if "firmware hotplug userspace" is not there yet or
-                it doesn't yet provide the needed firmware.
-                Once the firmware is widely available in userspace, it can be
-                removed from the kernel. Or made optional (CONFIG_.*_FIRMWARE).
-
-        In either case, if firmware hotplug support is there, it can move the
-        firmware out of kernel memory into the real filesystem for later
-        usage.
-
-        Note: If persistence is implemented on top of initramfs,
-        register_firmware() may not be appropriate.
