cannot do that when building for other architectures.
Add another Kconfig symbol to handle the SOC15 and navi, making

Many other drm drivers have the same dependency. It would be nice to
make this work in MMU-less configurations, but evidently nobody has

Move the shift into the division to make it apply on a 64-bit
variable. Also use the more expensive div64_u64() instead of div_u64()
to account for pxlclk being a 64-bit integer.
