Because of supporting Sscofpmf, Sstc extension, the local counter overflow interrupt (LCOFI,13) is implemented and writable.
While NEMU cannot get the value of counter, so we temporarily skip difftest ip CSRs in XiangShan.
Meanwhile, we update ie mask and hideleg/hedeleg mask to sync with XiangShan.
