[PATCH v4 1/4] firmware_loader: rename EXTRA_FIRMWARE and EXTRA_FIRMWARE_DIR

[Luis Chamberlain <mcgrof@kernel.org>]

Now that we've tied loose ends on the built-in firmware API,
rename the kconfig symbols for it to reflect more that they are
associated to the firmware_loader and to make it easier to
understand what they are for.
