65d437b83b drm/amdgpu/pm: fix the fan speed in fan1_input in manual mode for navi1x
It has been confirmed that the SMU metrics table should always reflect
the current fan speed even in manual mode.

10105d0c97 drm/amdgpu/swsmu: drop smu i2c bus on navi1x
Stop registering the SMU i2c bus on navi1x.  This leads to instability
issues when userspace processes mess with the bus and also seems to
cause display stability issues in some cases.

305a81bfbd drm/amdgpu/swsmu: fix ARC build errors
We want to use the dev_* functions here rather than the pr_* variants.
Switch to using dev_warn() which mirrors what we do on other asics.

Fixes the following build errors on ARC:

../drivers/gpu/drm/amd/amdgpu/../powerplay/navi10_ppt.c: In function 'navi10_fill_i2c_req':
../arch/arc/include/asm/bug.h:24:2: error: implicit declaration of function 'pr_warn'; did you mean 'drm_warn'? [-Werror=implicit-function-declaration]

../drivers/gpu/drm/amd/amdgpu/../powerplay/sienna_cichlid_ppt.c: In function 'sienna_cichlid_fill_i2c_req':
../arch/arc/include/asm/bug.h:24:2: error: implicit declaration of function 'pr_warn'; did you mean 'drm_warn'? [-Werror=implicit-function-declaration]

potentially sleeping if the smu message mutex is contended.
