cxl: fix CONFIG_FW_LOADER dependency

Browse source 
When FW_LOADER is disabled, cxl fails to link:

arm-linux-gnueabi-ld: drivers/cxl/core/memdev.o: in function `cxl_memdev_setup_fw_upload':
memdev.c:(.text+0x90e): undefined reference to `firmware_upload_register'
memdev.c:(.text+0x93c): undefined reference to `firmware_upload_unregister'

In order to use the firmware_upload_register() function, both FW_LOADER
and FW_UPLOAD have to be enabled, which is a bit confusing. In addition,
the dependency is on the wrong symbol, as the caller is part of the
cxl_core.ko module, not the cxl_mem.ko module.
