kernacc() expects all KVAs to be covered in the kernel map. With the
introduction of the PBVM, this stopped being the case. Redefine the
VM parameters so that the PBVM is included in the kernel map. In
particular this introduces VM_INIT_KERNEL_ADDRESS to point to the base
of region 5 now that VM_MIN_KERNEL_ADDRESS points to the base of
region 4 to include the PBVM.
While here define KERNBASE to the actual link address of the kernel as
is intended.
