Use the UEFI event timer to update the time on arm and arm64. The current
code uses the GetTime function from the Runtime Service, however this has
been shown to not return a useable time on many arm64 UEFI implementations.

Enable warnings in EFI boot code

Set WARNS if not set for EFI boot code and fix the issues highlighted by
setting it.

Most components are set to WARNS level 6 with few being left at lower
levels due to the amount of changes needed to fix at higher levels.

Error types fixed:
* Missing / invalid casts
* Missing inner structs
* Unused vars
* Missing static for internal only funcs
* Missing prototypes
* Alignment changes
* Use of uninitialised vars
* Unknown pragma (intrinsic)
* Missing types etc due to missing includes
* printf formatting types

UEFI: combine GetMemoryMap and ExitBootServices and retry on error

The EFI memory map may change before or during the first
ExitBootServices call. In that case ExitBootServices returns an error,
and GetMemoryMap and ExitBootServices must be retried.

Glue together calls to GetMemoryMap(), ExitBootServices() and storage of
(now up-to-date) MODINFOMD_EFI_MAP metadata within a single function.

That new function - bi_add_efi_data_and_exit() - uses space previously
allocated in bi_load_efi_data() to store the memory map (it will fail if
that space is too short). It handles re-calling GetMemoryMap() once to
update the map key if necessary. Finally, if ExitBootServices() is
successful, it stores the memory map and its header as MODINFOMD_EFI_MAP
metadata.

ExitBootServices() calls are now done earlier, from within arch-
independent bi_load() code.

Install the forth bits on arm64. For now limit it to just arm64 as on x86
these should have been installed as part of the regular loader.

Pass the ACPI table pointer to the arm64 kernel from loader.efi.

The self-relocation code is not efi-specific, move it to boot/common.

The function was defined as taking 4 parameters and returning EFI_STATUS,
but all existing callers (in asm code) passed only two parameters and don't
use the return value. The function signature now matches that usage, and
doesn't refer to efi-specific types.

Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.

The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.
