Removes very complex boot-time generation of page tables with a much simpler runtime generation of them at bootup. For those x86 boards that enable the MMU in the defconfig, set the number of page pool pages appropriately. The MMU_RUNTIME_* flags have been removed. They were an artifact of the old page table generation and did not correspond to any hardware state. Signed-off-by: Andrew Boie <andrew.p.boie@intel.com>
