in QEMU 7.1. Instead, use the `-display sdl,grab-mod=<modifiers>` option

Add a note on CPU features that are off by default in `virt` machines.
Some CPU features will remain off even if a CPU-capable CPU (e.g.,
`-cpu max`) is selected because they require support in both the CPU
itself and in the wider system. Therefore, the user, besides selecting a
CPU that supports such features, must also turn on the feature using a
machine option.

Currently, the documentation outlines the process for building the
S-mode U-Boot image using `make menuconfig` and manual actions within
the menuconfig UI. However, this approach is fragile due to Kconfig
options potentially changing across different releases. For example,
CONFIG_OF_PRIOR_STAGE has been replaced by CONFIG_BOARD since v2022.01
release, and CONFIG_TEXT_BASE has been moved to the 'General setup'
menu from the 'Boot options' menu in v2024.01 release.
This update aims to make the S-mode U-Boot image build instructions
future-proof. It leverages the 'config' script provided in the U-Boot
source tree to edit the .config file, followed by a `make olddefconfig`.
Validated with U-Boot v2024.01 release.
