The generic extension set 'G' is realy a base with the minimal set of
extensions needed to be comfortable (but not required) to run a
linux-bassed system. Similarly, we consider the custom to be about the
custom set of features (not about a custom core implementing such a
set).
As such, we allow that a core with the G set can have futher extensions
without requiring it to be configured as a custom set.
We drop the intermediate symbols with the prompts, and move the prompts
to the previously hidden symbols, and add a prompt for the I set.
This alows one to clearly see what the generic set is about, without
having to delve into the help and hunt the list of selected symbol.
Note however that the G set implies Zicsr and Zifencei, but we have no
prompt for thos two, because in Buildroot, we assume that they are
mandatory and always present, like the I set (which they previously were
part of).

BR2_RISCV_ISA_CUSTOM_RVA is currently not explicitly listed as it is
selected by BR2_riscv_custom. This looks confusing. Let's enable it.

With upstream commit ae2d9506a36c ("riscv: sifive: Rename fu540 board to unleashed")
in U-Boot v2021.07 release, the defconfig for SiFive Unleashed board
has been changed to sifive_unleashed_defconfig.
Also newer U-Boot has deprecated the usage of SPL_FIT_GENERATOR
to generate u-boot.itb hence there is no 'u-boot.itb' target in
the U-Boot Makefile anymore. Instead binman is used to assemble
the u-boot.itb image.
We will need to switch to BR2_TARGET_UBOOT_FORMAT_CUSTOM for
installing u-boot.itb.
Switch over to use the latest U-Boot v2023.04 release.

Since the rest of RISC-V boards have been switched to use OpenSBI
1.2, let's update hifive_unleashed to use OpenSBI 1.2 too.

Update to use the official linux kernel v5.10 instead of an
out-of-tree kernel, and use the official U-Boot v2021.01 as the
bootloader. Provide two configuration files of genimage for different
boot flows:
- Boot from SD card (default)
- Boot from SPI flash
A boot script is generated to automatically boot the distro.

[Thomas:
- fix the directory name hifive_unleased -> hifive-unleashed
- drop from readme.txt the instructions about manually flashing each
partition, since we have a full SD card image
- drop the custom post-image.sh script]
