Commit [1] introduced a new spike_riscv32_defconfig with Kernel
at v6.6.35.
This commit bumps the Kernel of spike_riscv64_defconfig to have it
aligned with its 32bit counterpart.
This commit also adds custom hashes. Therefore, it adds
BR2_DOWNLOAD_FORCE_CHECK_HASHES=y in the defconfig, adds a global
patch directory, and removes the entry in ".checkpackageignore".
Finally, to completely align with the spike_riscv32_defconfig, the
config directive BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM is moved by few
lines.
With this commit, the maintenance of the two spike_riscv{32,64}
defconfigs will be easier.

At the time the spike_riscv64_defconfig was introduced in commit [1], it
was not possible to have a console input using Spike and OpenSBI for
RISC-V 32 bits. This limitation no longer applies, as upstream
components now implements support for this.
Buildroot commit [2] updated riscv-isa-sim (Spike), which now includes a
NS16550 uart emulation. This can be used by RV32 Linux Kernel. Finally,
a spike_riscv32_defconfig was added in [3].
This commit removes the comment about this limitation, since it no
longer applies.

Buildroot commit [1] updated riscv-isa-sim (Spike), which now includes
a NS16550 uart emulation. This can be used by RV32 Linux Kernel. This
commit introduce a defconfig for running Linux on Spike RISC-V 32-bit
ISA simulator.

Buildroot commit [1] updated riscv-isa-sim (Spike), which now includes
a NS16550 uart emulation. The Kernel config fragment was introduced to
work with older HTIF interface from Spike.
For more information about the HTIF/NS16550 in Spike, see the commit
log [2].
This commit removes this Kernel config fragment, since it is no longer
needed.

Linux Kernel 6.1 now being officially promoted to be a LTS, this
commit bump the kernel version of this defconfig to 6.1.14.
A Kernel config fragment "linux.fragment" is now needed as the kernel
no longer enable SBI v0.1 support and the earlycon RISC-V SBI in its
riscv arch defconfig. See [1] [2].
The Spike riscv-isa-sim was updated upstream accordingly [3].
In order to keep a smooth transition, this kernel config fragment
re-enable those options to make sure this kernel will work with
both old Spike versions (not including commit [3] like the v1.1.0
currently included in Buildroot), and newer versions. This commit
was also successfully tested with riscv-isa-sim at commit
0d1a48c0c0.

commit 0d0f84d200
added the missing host-dtc dependency to riscv-isa-sim.
The spike simulator calls the dtc binary at its startup. The host dtc
command needs to be in the PATH at that time.
This commit add the buildroot host binary directory into the PATH of the
start.sh helper script. It make sure spike will use the buildroot dtc
version. This commit fixes this start.sh script on host not providing
the dtc command. Since the "spike" binary is now in the PATH, the
binary name is also simplified.
