linux-yocto.inc: remove riscv-isa-clear.scc from KERNEL_FEATURES_RISCV?

[Michael Opdenacker <michael.opdenacker@rootcommit.com>]

Greetings,

I'm getting the same issue trying a master build on several RISC-V boards:

ERROR: linux-milkv-duo-dev-1.0-r0 do_kernel_metadata: Feature 
'arch/riscv/tunes/riscv-isa-clear.scc' not found, this will cause 
configuration failures.
ERROR: linux-milkv-duo-dev-1.0-r0 do_kernel_metadata: Check the SRC_URI 
for meta-data repositories or directories that may be missing
ERROR: linux-milkv-duo-dev-1.0-r0 do_kernel_metadata: Set 
KERNEL_DANGLING_FEATURES_WARN_ONLY to ignore this issue

OK, I can set
KERNEL_DANGLING_FEATURES_WARN_ONLY = "1"
but is this a clean solution?

Where are all the arch/riscv/tunes/riscv-isa-*.scc files supposed to be?
I didn't manage to find them anywhere...

Thanks in advance
Cheers
Michael.
