drm/mode_config: Make drm_mode_config.(max|min)_(width|height) unsigned

Browse Source 
It doesn't make much sense to allow devices to specify their min/max
resolution as signed integers, and in Rust with CONFIG_RUST_OVERFLOW_CHECKS
enabled this provides us actual over/underflow checks. Similarly, it
doesn't really make much sense for us to allow devices to specify their
minimum/maximum resolution as signed.
