Patrick Rudolph c1b7e8a60b cpu/x86/pae/pgtbl: Add memset with PAE
To clear all DRAM on x86_32, add a new method that uses PAE to access
more than 32bit of address space.
Add Documentation as well.

Required for clearing all system memory as part of security API.

Tested on wedge100s:
 Takes less than 2 seconds to clear 8GiB of DRAM.
Tested on P8H61M-Pro:
 Takes less than 1 second to clear 4GiB of DRAM.
