[llvm] [RISCV] Remove zfbfmin.ll. NFC (PR #106937)

[Craig Topper via llvm-commits]

https://github.com/topperc created https://github.com/llvm/llvm-project/pull/106937

Most of it is redundant with bfloat-convert.ll. One testcase is found in bfloat-imm. The load and stores are more thoroughly tested in bfloat-mem.ll.
