prism54-firmware: set DL_DIR to package specific subdirectory
This package downloads raw files
which have names that are not corresponding to
the name and version of the package
as it is defined in the Makefile.
Use the option DL_SUBDIR to set the DL_DIR
to be a subdirectory named with
PKG_NAME and PKG_RELEASE
to better organize the downloads.
