[PATCH V3 0/6] Improve the U/S/H extension related check

[Weiwei Li]

This patchset tries to improve the U/S/H related check:
* add check for the supported privilege modes conbinations: only supporting M,
S mode is not a suggested combination
* add check for "H extension depends on I extension"
* add check for "H extension implicitly requires S mode"
* add check for csrs only existed when U mode is supported
* fix and simplify the checks in hmode/hmode32

Any suggestions are welcome.

v3:
* Fix the issues suggested by Andrew Jones in commit messages

v2:
* update patch 3 to make the newlines start at the same position as above line
* update patch 5 to add check for "H extension implicitly requires S mode"
