x86: implement true end_pfn_mapped for 32bit
Even on 32bit 2MB pages can map more memory than is in the true max_low_pfn if end_pfn is not highmem and not aligned to 2MB. Add a end_pfn_map similar to x86-64 that accounts for this fact. This is important for code that really needs to know about all mapping aliases.
