[PATCH 0/4] Add Svadu extension support

[Yong-Xuan Wang]

This series enables Svadu extension support by configuring the menvcfg
CSR and, if available, displays the Svadu extension in the boot log. 

Additionally, we've made some programming improvements in
lib/sbi/sbi_hart.c.

  lib: sbi: refactor the code for enable extensions in menvfg CSR
  lib: sbi: Add support for Svadu extension
  lib: sbi: Improve the code of privilege mode and extensions detection
  lib: sbi: detect extensions from menvcfg
