Expose both SMU I2C buses. Some boards use the same bus for both the RAS
and FRU EEPROMs and others use different buses.  This enables the
additional I2C bus and sets the right buses to use for RAS and FRU EEPROM
access.

<title>drm/amdgpu: Add kernel parameter support for ignoring bad page threshold</title>

When a GPU hits the bad_page_threshold, it will not be initialized by
the amdgpu driver. This means that the table cannot be cleared, nor can
information gathering be performed (getting serial number, BDF, etc).

If the bad_page_threshold kernel parameter is set to -2,
continue to initialize the GPU, while printing a warning to dmesg that
this action has been done

is at 90% or greater for easier checks and planning, instead of waiting

This was unusual; normally, inline functions are declared static as
well, and defined in a header file if used by multiple compilation
units. The latter would be more involved in this case, so just drop
the inline declaration for now.
