[PATCH] fs: Fix SPL build if SPL_FS_LOADER is enabled and FS_LOADER is disabled

[Hiago De Franco]

From: Hiago De Franco <hiago.franco at toradex.com>

When SPL_FS_LOADER is set to y and FS_LOADER is not enabled, the SPL build
fails with the following errors:

  AR      spl/boot/built-in.o
  LD      spl/u-boot-spl
arm-none-linux-gnueabihf-ld.bfd: drivers/misc/fs_loader.o: in function
`fw_get_filesystem_firmware':
/u-boot/drivers/misc/fs_loader.c:162: undefined reference to
`fs_set_blk_dev'
arm-none-linux-gnueabihf-ld.bfd: /home/frh/tdx/src/u-boot/drivers/misc/
fs_loader.c:185: undefined reference to `fs_read'
arm-none-linux-gnueabihf-ld.bfd: drivers/misc/fs_loader.o: in function
`select_fs_dev':
/u-boot/drivers/misc/fs_loader.c:89: undefined reference to

make[1]: *** [scripts/Makefile.spl:527: spl/u-boot-spl] Error 1
make: *** [Makefile:2055: spl/u-boot-spl] Error 2

Fix it by replacing the FS_LOADER with SPL_FS_LOADER in the Makefile, so
the fs.c with the necessary function definitions are compiled.

Fixes: b071a07743d4 ("drivers: misc: Makefile: Enable fs_loader compilation at SPL Level")
