The binutils has not supported zama16b. Do not enable the extension
through -mcpu=xt-c9501fdvt.
gcc/ChangeLog:
* config/riscv/riscv-cores.def (RISCV_CORE): Remove zama16b from
xt-c9501fdvt.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/mcpu-xt-c9501fdvt.c: Expect __riscv_zama16b
to be undefined.

The zama16b extension is not supported at gas(https://godbolt.org/z/ed1EdfaKr),
and there already were two patches to support it but neither received
feedback. It seems unlikely that the support will land in the near term.
