target/riscv/tcg: use only isa_edata_arr[] in cpu_cfg_ext_get_name()

We're using both isa_edata_arr[] and riscv_cpu_named_features[] to find
an extension name based on a cfg offset.  This is reminiscent of a past
where isa_edata_arr[] didn't include entries for internal extensions.

At this point we can use just isa_edata_arr[].
