boot/xilinx-embeddedsw: change dependency

Now that BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH can contain multiple tuples,
BR2_TARGET_XILINX_EMBEDDEDSW can no longer be dependent on:

depends on BR2_TOOLCHAIN_BARE_METAL_BUILDROOT_ARCH = "microblazeel-xilinx-elf"

A valid definition could have "microblazeel-xilinx-elf" as just one of many
tuples in the list.

For this reason, this patch changes the dependency to:

depends on BR2_TOOLCHAIN_BARE_METAL_BUILDROOT

One side effect of this is that the user comment will be displayed now when
using multiple tuples, even if one of them is the required tuple.
