This installs all the in-kernel-tree firmware into $(INSTALL_FW_PATH), which defaults to $(objtree)/usr/lib/firmware and is intended end up in /lib/firmware for udev to find the files.
This, in conjunction with the builtin-firmware support, makes it simple for drivers with associated firmware to move over to request_firmware() and give the user a choice of whether to have it built in to the kernel image or loaded separately from userspace.
As with kernel header installation for userspace, it intentionally pays no attention to configuration variables -- it installs _all_ available firmware blobs, unconditionally.
