Revert 'x86: Fix system crash when loading with "reservetop" parameter'
After close looking, commit
8126dec3 will break:
1. some cpu feature in early stage too, like cpu_has_x2apic
2. will break built-in-command line
3. will break other memmap= and mem=
4. early_dbgp and early_console that will use early_ioremap to access mmio (?)
So revert it.
