On the SM8550 SoC, some nodes requires a specific bit mark

Would be nice to mention that it's literally this commit:
https://git.codelinaro.org/clo/la/kernel/msm-5.15/-/commit/2d1573e0206998151b342e6b52a4c0f7234d7e36
Good catch, I just copied the bits but yeah in fine it's the same...
I'll refer to it in a v2.
For the code:
