  1. riscv: mm: support icache&tlb HW broadcast on xuantie 

    By configuring `flush-tlb-range` and `flush-icache-range` in DTS to enable the
HW broadcast feature of Xuantie CPU, soft broadcasting is avoided and system
performance is improved.

The DTS example as follows:
```
cpus {
    ...
    flush-icache-range = <1>;
    flush-tlb-range = <1>;
    cpu@0 {
    ...
```
