Build is failing with an unrecognised opcode error due to missing
`zicsr` extension requirement. This is introduced with GCC version 12.
When binutils was updated to v2.38 they updated to the default ISA spec
version 20191213. In this version the original i extension split into i,
Zicsr and Zifencei. A fix for this has been added since U-Boot version
2022.01 to detect new Zicsr and Zifencei extensions and enable it when needed
therefore, an updated U-Boot tag to our latest 2023.09 release will fix
this as in our latest release we have updated to U-Boot version 2023.07.
Update the kernel verion in line with the U-Boot release version to
ensure compatiblities and latest features and fixes are included.
Remove riscv_g selection as it is now selected by default.

Update the instruction sets for MPFS icicle kit to mirror the
configuration update, i.e. It is now classed as a RISC-V G core with
support for C, IMAFDC.

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).

Add support for the icicle kit, the main development board for
Microchip's PolarFire SoC.
The configuration file is microchip_mpfs_icicle_defconfig. It builds a
bootable kernel image with an embedded root file system. The image
built can be flashed to the board using the eMMC or an SD card.
The yaml configuration file is used by the hss payload generator. It
maps the ELF binaries or binary blobs to the individual application
harts (U54s).
The image generator script sets the partitions of the image.
The kernel fragment file sets additional configurations for the icicle
kit in buildroot that are not in the default configuration.
The image tree souce file creates a FIT image.
The post image script creates the payload using the payload generator
host package and finally, creates the FIT image using the ITS after the
kernel build.
The U-Boot script and additional U-Boot configurations ensure that
U-Boot behaves as expected for the icicle kit and boots the FIT image.
The readme.txt file documents how to build and boot the icicle kit with
this configuration.
