[Why] This function takes an offset and a length as argument, not a physical address and a number of pages. This misuse caused the `set_memory_*()` and `arch_io_reserve_memtype_wc()` functions to return EINVAL. Another problem was the fact that they returned errors as a positive integer, whereas Linux uses negative integers. [How] Physical addresses and number of pages are converted to offset+length in the `set_memory_*()` functions. `arch_io_reserve_memtype_wc()` now calls `pmap_change_attr()` directly instead of using `set_memory_wc()`.
