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

The beaglev kernel is based on the 5.13 branch, update
the expected linux-headers version to 5.13.
This has been wrong ever since the bump of the kernel version in commit
9a1bd7cc1c: the headers were bumped to
5.12 instead of 5.13.

Switch from the starfive-tech opensbi to upstream repo and use generic
platform now that it supports the console uart [1]. This landed after
the 0.9 release [2], so the current head of master branch is used [3].
FW_FDT_PATH is set to u-boot.dtb so that the device tree from U-Boot
will be included in the OpenSBI build [4]. Note that U-Boot must have
CONFIG_OF_SEPARATE enabled for U-Boot to build u-boot.dtb [5].

The commit abb06422a5cd ("Remove fdt_high and initrd_high for Starfive")
has removed the need for buildroot to patch the fdt_addr_r address.
Update linux from commit in the old 5.10 branch that Fedora image was
using to head of esmil_starlight branch [1] which is currently based
on 5.13-rc5 and represents the best kernel for this board [2]. This
commit was tagged as buildroot-20210609 because the branch gets rebased
regularly.
In addition, the updated kernel now has jh7100-beaglev-starlight.dtb so
buildroot no longer needs to copy the dtb from u-boot.
