package/qoriq-cadence-dp-firmware: also install to target if needed

This firmware is loaded by U-Boot, so when U-Boot is loading the Linux
kernel from the root filesystem, it is very likely that it will also
want to load this firmware from the root filesystem.

Therefore, this patch makes sure that that Cadence DP firmware is
installed alongside the kernel image in /boot in the root filesystem
when the kernel is installed
there (BR2_LINUX_KERNEL_INSTALL_TARGET=y).

We keep installing the firmware in $(BINARIES_DIR) in any case.
