drm/amdgpu: bump minor version number for DEV_INFO and SENSOR IOCTLs update

Update AMDGPU_INFO_DEV_INFO IOCTL for minimum engine and memory clock.
And update AMDGPU_INFO_SENSOR IOCTL for PEAK_PSTATE engine and memory clock.
User applications can better utilize these IOCTLs to get needed informations.

Increase the minor version number to indicate that the new flags are
available.
