The package/busybox/busybox-minimal.config is the default configuration
for MMU-less systems, so the setting is redundant and can be removed
without effect.

Bump the kernel version for all riscv nommu configs from 5.18 to 5.19.
That way, we can remove the one and only riscv nommu patch,
since this patch is included in kernel 5.19.

The MMU option is currently located in the "Toolchain" menu, but it
doesn't make sense as it's really architecture related. In addition,
the selection of MMU has an impact on the choice of binary format
available, which is visible in the architecture menu.
Therefore, this commit moves the MMU option into the architecture
menu.
However, if we simply move it in arch/Config.in, it means that we
would have the following order of options:
Target architecture
Target architecture variant
ABI
MMU
Binary format
But really, the MMU option should be right below the Target
architecture variant, and the available ABIs derived from that.
The variant and ABI are arch-specfic, and defined in the per-arch
Config.in fragments; a Kconfig option can have only one prompt defined,
even under conditions, and appears at the place in the menu where its
prompt was defined. So, there is no (easy) possibility to have a
generic option appear where we want it.
Since in fact only 2 architectures show a visible prompt for the MMU
option (RISC-V and Xtensa), we move this option in
arch/Config.in.riscv and arch/Config.in.xtensa.
Some walkthrough the commit:
- BR2_ARCH_HAS_MMU_MANDATORY and BR2_ARCH_HAS_MMU_OPTIONAL are
removed as they are no longer needed
- BR2_USE_MMU becomes a hidden boolean
- All the places where we used to select BR2_ARCH_HAS_MMU_MANDATORY
now select BR2_USE_MMU directly.
- Introduce BR2_RISCV_USE_MMU and BR2_XTENSA_USE_MMU.
- All defconfigs that used "# BR2_USE_MMU is not set" are switched to
using the new option.
All in all, this simplifies things quite a bit, and allows to have a
good option ordering in the Target architecture menu.
This commit might raise a concern in terms of backward compatibility
with existing configurations. The only configurations that will be
broken by this change are RISC-V noMMU (which was very recently
introduced) and Xtensa noMMU (which we can probably agree is not such
a widely popular configuration).

There is no need to have configuration files direbtly set the
BR2_PACKAGE_HOST_ELF2FLT option. The need for the elf2flt utility is
automatically determined by gcc build in package/gcc/gcc.mk according to
the BR2_BINFMT_FLAT option.
Accordingly, we can remove the file package/elf2flt/Config.in.host to
get rid of the BR2_PACKAGE_HOST_ELF2FLT option. BR2_STRIP_strip
dependency on this option is replaced with a dependency on
BR2_BINFMT_ELF.
To stay consistent with the fact that elf2flt supports only the arm, sh,
sparc, xtensa and riscv-64 architectures, a dependency on these
architectures is added to the BR2_BINFMT_FLAT option in arch/Config.in.
Board configuration files setting the BR2_PACKAGE_HOST_ELF2FLT option
are also updated.

Add RISC-V 64-bit nommu defconfig for QEMU virt machine with MMU
disabled.
Unlike qemu_riscv64_virt, qemu_riscv64_nommu_virt does not use OpenSBI,
since the kernel is running in machine mode (M-mode).
After the build is complete, you can start QEMU using the launcher
script:
