docs/system/riscv: sifive_u: Update S-mode U-Boot image build instructions

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CONFIG_OF_PRIOR_STAGE has been replaced by CONFIG_BOARD since v2022.01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.

docs/system/riscv: sifive_u: Update U-Boot instructions

In U-Boot v2021.07 release, there were 2 major changes for the
SiFive Unleashed board support:

- Board config name was changed from sifive_fu540_defconfig to
sifive_unleashed_defconfig
- The generic binman tool was used to generate the FIT image
(combination of U-Boot proper, DTB and OpenSBI firmware)

which make the existing U-Boot instructions out of date.

Update the doc with latest instructions.
