We can pass SMBIOS easily as EFI configuration table to an EFI payload. This
patch adds enablement for that case.
While at it, we also enable SMBIOS generation for ARM systems, since they support
EFI_LOADER.

The SMBIOS generation code passes pointers as u32. That causes the compiler
to warn on casts to pointers. This patch moves all address pointers to
uintptr_t instead.
Technically u32 would be enough for the current SMBIOS2 style tables, but
we may want to extend the code to SMBIOS3 in the future which is 64bit
address capable.

EFI allows an OS to leverage firmware drivers while the OS is running. In the
generic code we so far had to stub those implementations out, because we would
need board specific knowledge about MMIO setups for it.
However, boards can easily implement those themselves. This patch provides the
framework so that a board can implement its own versions of get_time and
reset_system which would actually do something useful.
While at it we also introduce a simple way for code to reserve MMIO pointers
as runtime available.

Currently each allocation creates a new mapping. Readding the mapping
as free memory (EFI_CONVENTIONAL_MEMORY) potentially allows to hand out
an existing mapping, thus limiting the number of mapping descriptors in
the memory map.
Mitigates a problem with current (4.8rc7) linux kernels when doing an
efi_get_memory map, resulting in an infinite loop. Space for the memory
map is reserved with allocate_pool (implicitly creating a new mapping) and
filled. If there is insufficient slack space (8 entries) in the map, the
space is freed and a new round is started, with space for one more entry.
As each round increases requirement and allocation by exactly one, there
is never enough slack space. (At least 32 entries are allocated, so as
long as there are less than 24 entries, there is enough slack).
Earlier kernels reserved no slack, and did less allocations, so this
problem was not visible.

We need a functional free_pool implementation, as otherwise each
allocate_pool causes growth of the memory descriptor table.
Different to free_pages, free_pool does not provide the size for the
to be freed allocation, thus we have to track the size ourselves.
As the only EFI requirement for pool allocation is an alignment of
8 bytes, we can keep allocating a range using the page allocator,
reserve the first 8 bytes for our bookkeeping and hand out the
remainder to the caller. This saves us from having to use any
independent data structures for tracking.
To simplify the conversion between pool allocations and the corresponding
page allocation, we create an auxiliary struct efi_pool_allocation.
Given the allocation size free_pool size can handoff freeing the page
range, which was indirectly allocated by a call to allocate_pool,
to free_pages.

We currently handle efi_allocate_pool() in our boot time service
file. In the following patch, pool allocation will receive additional
internal semantics that we should preserve inside efi_memory.c instead.
As foundation for those changes, split the function into an externally
facing efi_allocate_pool_ext() for use by payloads and an internal helper
efi_allocate_pool() in efi_memory.c that handles the actual allocation.
While at it, change the magic 0xfff / 12 constants to the more obvious
EFI_PAGE_MASK/SHIFT defines.

Sometimes devicetree nodes and or properties are added out of the u-boot
console, maybe through some script or manual interaction.
The devicetree as loaded or embedded is quite small, so the devicetree
has to be resized to take up those new nodes/properties.
In original the devicetree was only extended by effective
4 * add_mem_rsv.
With this commit we can add an argument to the "fdt resize" command,
which takes the extrasize to be added.
