[PATCH v2 0/5] Add Svadu extension support

[Yong-Xuan Wang <yongxuan.wang@sifive.com>]

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 and lib/utils/fdt/fdt_helper.c.

---
v2:
- Rearrange the patches to do the code refactoring first before adding
  new features
- Suggested by Anup and Atish, detect extensions from DT instead of
  menvcfg CSR
- Enable access to some extensions through menvcfg CSR if they are
  present in the device tree.

  lib: sbi: Improve the code of privilege mode and extensions detection
  lib: sbi: Refactor the code for enable extensions in menvfg CSR
  lib: sbi: Using one array to define the name of extensions
  lib: sbi: Detect extensions from the ISA string in DT
  lib: sbi: Add support for Svadu extension
