The same Kconfig statement 'depends on RISCV_ISA_V' appears twice for
RISCV_PROBE_VECTOR_UNALIGNED_ACCESS. The first instance is in its choice
menu, "Vector unaligned Accesses Support", making the second instance in
its specific Kconfig definition dead code. I propose removing this second
instance.
This dead code was found by kconfirm, a static analysis tool for Kconfig.

During boot, the kernel will run a series of tests to determine the
speed of vector unaligned accesses if they are supported. This probing
