riscv: Define __riscv_copy_{,vec_}{words,bytes}_unaligned() using SYM…
70d3902 
…_TYPED_FUNC_START

After commit 67bdd7b ("riscv: Split out measure_cycles() for
reuse") and commit c03ad15 ("riscv: Reuse measure_cycles() in
check_vector_unaligned_access()"), there are CFI failure when booting
kernels with CONFIG_CFI=y:

  CFI failure at measure_cycles+0x38/0xe0 (target: __riscv_copy_words_unaligned+0x0/0x50; expected type: ...)
  CFI failure at measure_cycles+0x38/0xe0 (target: __riscv_copy_vec_words_unaligned+0x0/0x24; expected type: ...)

The __riscv_copy_*_unaligned() functions are now called indirectly but
they are not defined with SYM_TYPED_FUNC_START, which is required for
assembly functions called indirectly from C to pass CFI checking. Switch
to SYM_TYPED_FUNC_START to clear up the CFI failures.

Fixes: 67bdd7b ("riscv: Split out measure_cycles() for reuse")
Fixes: c03ad15 ("riscv: Reuse measure_cycles() in check_vector_unaligned_access()")

riscv/sifive: remove warning in errata
9670160 
The patch_id of the availability checking for SiFive vendor extensions
will always larger than ERRATA_SIFIVE_NUMBER. Remove this unnecessary
warning.
