x86: pat: Remove ioremap_default()
Commit: b6ff32d: x86, PAT: Consolidate code in pat_x_mtrr_type() and reserve_memtype() consolidated reserve_memtype() and pat_x_mtrr_type, this made ioremap_default() same as ioremap_cache(). Remove the redundant function and change the only caller to use ioremap_cache.
