Update to support EFI runtime outside the kernel virtual address space
by creating an EFI RT pmap that can be activated / deactivated when
required.

Adds support for EFI RT to ARM_MMU_EXTENDED (ASID) 32-bit Arm machines.

On Arm64 the usage of pmapboot_enter is reduced and the mappings are
created much later in the boot process -- now in cpu_startup_hook.
Backward compatiblity for KVA mapped RT from old bootaa64.efi is
maintained.

Adding support to other platforms should be easier as a result.

Use sys/uvm/pmap/pmap_tlb.c on Aarch64 in the same way that some Arm, MIPS,
and some PPC kernels do.  This removes the limitation of 256 processes on
CPUs with 8bit ASID field, e.g. Apple M1.

Additionally the following changes have been made

- removed a couple of unnecessary aarch64_tlbi_all calls
- removed any invalidation after freeing page tables due to
  _pmap_sweep_pdp. This was never necessary afaict.
- all kernel mappings are marked global and userland mapping not-global.

Performance testing hasn't show a significant difference.  The data here
is from building a kernel on an lx2k system with nvme.

Part IV of ad's performance improvements for aarch64

- Implement pmap_growkernel(), and update kernel pmap's stats with atomics.

- Then, pmap_kenter_pa() and pmap_kremove() no longer need to allocate
  memory nor take pm_lock, because they only modify L3 PTEs.

- Then, pm_lock and pp_lock can be adaptive mutexes at IPL_NONE which are
  cheaper than spin mutexes.

- Take the pmap's lock in pmap_extract() if not the kernel's pmap, otherwise
  pmap_extract() might see inconsistent state.

pmapboot_enter simplication
- bootpage_alloc in asm becomes pmapboot_pagealloc in C
- PMAPBOOT_ENTER_NOBLOCK is removed as it's not used
- PMAPBOOT_ENTER_NOOVERWRITE is removed as it's now always on
- physpage_allocator argument is removed as it's always
  pmapboot_pagealloc
- Support for EARLYCONS without CONSADDR is removed so that the identity
  map for CONSADDR is always known.

Changes since 1.39: +16 -12 lines
Diff to previous 1.39 (colored)

- Fix a lock order reversal in pmap_page_protect().

- Make sure pmap is always locked when updating stats; atomics no longer
  needed to do that.

- Remove unneeded traversal of pv list in pmap_enter_pv().

- Shrink struct vm_page from 136 to 128 bytes (cache line sized) and struct
  pv_entry from 48 to 32 bytes (power of 2 sized).

- Embed a pv_entry in each vm_page.  This means PV entries don't need to
  be allocated for private anonymous memory / COW pages / most UBC mappings.
  Dynamic PV entries are then used only for stuff like shared libraries and
  shared memory.

Proposed on port-arm@.

use PMAP_PAGE_INIT() to initialize mutex in pmap_page.

VM_MDPAGE_INIT() in pmap_free_pdp() had initialized pp_flags,
so it unintentionally cleared PMAP_PAGE_FLAGS_PV_TRACKED.
use PMAP_PAGE_INIT to avoid using PMAP_PAGE_FLAGS_PV_TRACKED.

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors.  AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested.  Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

cleanup locore, and changed the way to map memories during boot.
- add functions bootpage_enter() and bootpage_alloc() to adapt various layout
  of physical memory map. especially for 64bit physical memory layout.
  pmapboot_alloc() allocates pagetable pages from _end[].
- changed to map only the required amount for PA=VA identity mapping
  (kernel image, UART device, and FDT blob) with L2_BLOCK(2Mbyte).
- changing page permission for kernel image, and making KSEG mapping are done
  at cpu_kernel_vm_init() instead of at locore.
- optimize PTE entries with PTE Contiguous bit. it is enabled on devmap only for now.

reviewed by skrll@, thanks.
