Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

to_fw_sysfs() was changed in commit 23680f0b7d7f ("driver core: make
struct class.dev_uevent() take a const *") to pass in a const pointer
but not pass it back out to handle some changes in the driver core.
That isn't the best idea as it could cause problems if used incorrectly,
so switch to use the container_of_const() macro instead which will
preserve the const status of the pointer and enforce it by the compiler.

The dev_uevent() in struct class should not be modifying the device that
is passed into it, so mark it as a const * and propagate the function
signature changes out into all relevant subsystems that use this
callback.

In the case of firmware-upload, an instance of struct fw_upload is
allocated in firmware_upload_register(). This data needs to be freed
in fw_dev_release(). Create a new fw_upload_free() function in
sysfs_upload.c to handle the firmware-upload specific memory frees
and incorporate the missing kfree call for the fw_upload structure.

Fix the CONFIGs around register_sysfs_loader(),
unregister_sysfs_loader(), register_firmware_config_sysctl(), and
unregister_firmware_config_sysctl(). The full definitions of the
register_sysfs_loader() and unregister_sysfs_loader() functions should
be used whenever CONFIG_FW_LOADER_SYSFS is defined. The
register_firmware_config_sysctl() and unregister_firmware_config_sysctl()
functions should be stubbed out unless CONFIG_FW_LOADER_USER_HELPER
CONFIG_SYSCTL are both defined.

Extend the firmware subsystem to support a persistent sysfs interface that
userspace may use to initiate a firmware update. For example, FPGA based
PCIe cards load firmware and FPGA images from local FLASH when the card
boots. The images in FLASH may be updated with new images provided by the
user at his/her convenience.
A device driver may call firmware_upload_register() to expose persistent
"loading" and "data" sysfs files. These files are used in the same way as
the fallback sysfs "loading" and "data" files. When 0 is written to
"loading" to complete the write of firmware data, the data is transferred
to the lower-level driver using pre-registered call-back functions. The
data transfer is done in the context of a kernel worker thread.

In preparation for sharing the "loading" and "data" sysfs nodes with the
new firmware upload support, split out sysfs functionality from fallback.c
and fallback.h into sysfs.c and sysfs.h. This includes the firmware
class driver code that is associated with the sysfs files and the
fw_fallback_config support for the timeout sysfs node.
CONFIG_FW_LOADER_SYSFS is created and is selected by
CONFIG_FW_LOADER_USER_HELPER in order to include sysfs.o in
firmware_class-objs.
This is mostly just a code reorganization. There are a few symbols that
change in scope, and these can be identified by looking at the header
file changes. A few white-space warnings from checkpatch are also
addressed in this patch.
