This patch series introduce support for the new-generation Hygon
models 0x4-0x8 processors, addressing five key areas:

1. CPU Topology Updates
The new processor introduces a revised CPU topology hierarchy
compared to previous generations. This patch updates the kernel's
topology detection logic to correctly identify core/socket
relationships and cache sharing patterns.

2. L3 Performance Monitoring Updates
The L3 perf registers of model 6h differ from those of the
previous processor.

3. Microcode loading
Add microcode loading support for Hygon processor.

4. Audio Controller Driver
Add initial support for the integrated HD-Audio controller.

5. New SB IOAPIC information support
The southbridge IOAPIC of Hygon's new-generation processors is
located at 00:0b.0.

v1->v2:
  - Refine the patch x86/cpu/hygon.
  - Do a separate compilation unit on hygon microcode loading support.
  - Use "access_sdnctl_in_dword" instead of "hygon_dword_acess" for
    accessing the HDA registers.

Thanks for your patch series.

I've tested the changes on my hygon servers (model 4h, 6h, 7h, 8h)  
with kernel version 7.0.0-rc7 and everything works as expected.
