doc: sifive-fu540: Update README to explicitly load DTB for Linux

We should explicitly load DTB from TFTP server or MMC/SD card
for Linux booting. This will allow us:
1. To use different Linux DTB for SiFive Unleashed board with
   expansion board connected.
2. Avoid re-flashing OpenSBI firmware whenever board connections
   change.

This patch updates reference bootlog in SiFive FU540 README
as-per above.
