When compiling the firmware loader, the builtin firmware functions were
erroneously compiled as they were wrapped with CONFIG_FW_LOADER instead
of CONFIG_FIRMWARE_IN_KERNEL. This is normally harmless, except when
there was actually no firmware to compile into the kernel, causing the
build to fail with a linking error:
drivers/built-in.o: In function `release_firmware':
(.text+0x192e2): undefined reference to `__end_builtin_fw'
drivers/built-in.o: In function `release_firmware':
(.text+0x19304): undefined reference to `__end_builtin_fw'
drivers/built-in.o: In function `_request_firmware':

drivers/built-in.o: In function `release_firmware':

drivers/built-in.o: In function `_request_firmware':

firmware_class.c:(.text+0x19a8a): undefined reference to `__start_builtin_fw'
This trivial patch fixes this oversight.
