With QEMU v4.2 RISC-V changes to improve the emulation fidelity
of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10 / Linux
kernel v5.3 images built for the SiFive HiFive Unleashed board
can be used out of the box without any special hack. Hence there
is no need for us to continue supporting such a special target in
OpenSBI. Going forward, sifive/fu540 platform can be used on both
real hardware and QEMU 'sifive_u' machine.

With U-Boot v2020.01, the SiFive FU540 DTB required by U-Boot is
embedded in U-Boot binary itself so we don't need to do anything
special for U-Boot v2020.01 as payload to OpenSBI firmware.
This patch updates SiFive FU540 documenation assuming we use
latest U-Boot v2020.01 release.

With QEMU v4.2 release that has improved the emulation fidelity
of 'sifive_u' machine, OpenSBI v0.4 / U-Boot v2019.10-rc1 / Linux
kernel v5.3-rc2 images built for the SiFive HiFive Unleashed board
can be used out of the box without any special hack.
Update our documents to mention 'qemu/sifive_u' platform should
only be used with QEMU v4.1 or before, and it will be dropped
sometime in the future release.
Going forward, 'sifive/fu540' platform can be used on both real
hardware and QEMU v4.2+ 'sifive_u' machine.

The Linux kernel will maintain the device tree (DT) for HiFive Unleashed
from release v5.2-rc6. This DT is incompatible with previous DT
present for Microsemi expansion board in OpenSBI.
Since, OpenSBI will directly load the pre-built DTB from kernel now onwards,
no need to keep the out-of-date DT in openSBI. Remove this DT and
it's related documentation.

- Correct the payload address in the RV64 examples that use
fw_jump.elf.
- Change the qemu console configuration in the examples from
"-display none -serial stdio" to "-nographic". This results in
qemu handing down a CTRL-C on the emulated console to the VM
instead of terminating the qemu process.
- Provide examples for RV32.
