Add sensors from Vega 10 and later series

[PatrickSzela]

According to the Linux Kernel Documentation with Vega 10 and 20 series the driver exposes some additional interfaces.

I would be grateful if someone with card from these series would upload (from /sys/bus/pci/drivers/amdgpu/<PCI_SLOT>/ directory) content of these files:

1. Vega 10 and later:
   1. pp_dpm_socclk ✅
   2. pp_dpm_dcefclk ✅
2. Vega 20 and later:
   1. pp_dpm_fclk ✅

From my Vega 64 (Vega10):

• pp_dpm_socclk:

0: 600Mhz *
1: 720Mhz
2: 800Mhz
3: 847Mhz
4: 900Mhz
5: 960Mhz
6: 1028Mhz
7: 1107Mhz

• pp_dpm_dcefclk:

0: 600Mhz *
1: 720Mhz
2: 800Mhz
3: 847Mhz
4: 900Mhz

Thank you for sharing the content of these files!
So it looks like, in comparison to other pp_dpm_* files, the current state of socclk and dcefclk isn't marked at all (with a *). Interesting... I guess it's time to dig in into the driver's source code.

My mistake. I accidentally deleted the * since I just thought you wanted the different state. Since the card was idling when I was posting, a * was used on state 0 on both. I've updated the original comment.

Thank you for the update! In that case, these 2 sensors will be added soon(-ish)

Hello, I have a RX 5700 XT (Navi 10). The contents of pp_dpm_fclk are:

0: 506Mhz 
1: 950Mhz *
2: 1266Mhz 

EDIT: Formatting

Thank you all for sending me these files! I've managed to get all three sensors to work - while using my "dummy files" - and I hope it will also work with the actual ones.
