uvesafb: Clean up MTRR code
The old code allowed very strange memory types. Now it works like all the other video drivers: ioremap_wc is used unconditionally, and MTRRs are set if PAT is unavailable (unless MTRR is disabled by a module parameter). UC, WB, and WT support is gone. If there are MTRR conflicts that prevent addition of a WC MTRR, adding a non-conflicting MTRR is pointless; it's better to just turn off MTRR support entirely. As an added bonus, any MTRR added is freed on unload.
