[PATCH 1/1] RISC-V: Imply 'Zicsr' from 'Zve32x'

[Tsukasa OI]

From: Tsukasa OI <research_trasio@irq.a4lg.com>

Further clarification is made so that 'Zve32x' implies 'Zicsr' (the same
implication is already implemented in LLVM).

See related issue (the author raised) on the vector specification:
<https://github.com/riscv/riscv-v-spec/issues/908>
and its resolution:
<https://github.com/riscv/riscv-v-spec/issues/909>

bfd/ChangeLog:

	* elfxx-riscv.c (riscv_implicit_subsets): Add 'Zve32x' -> 'Zicsr'.
