core_init_mmu_map() uses a temporary dummy memory map for the
virt_to_phys() and phys_to_virt() conversions to avoid asserting while
setting up translation tables before the MMU is enabled. CFG_DYN_CONFIG
will need a larger range of memory since translation tables might not be
allocated from .nozi memory only. So for CFG_DYN_CONFIG extend of end of
the unused memory range that the boot_mem_*() functions allocate memory
from.
Introduce CFG_DYN_CONFIG, enabled by default if CFG_BOOT_MEM is enabled
and CFG_WITH_PAGER disabled. CFG_DYN_CONFIG conflicts with
CFG_WITH_PAGER since the pager uses a different mechanism for memory
allocation.
