Remove some pointless #ifdefs from this file, as there are quite too
many of them already.
Some definitions don't really hurt to have in any case, so remove the
pointless CONFIG_MMC guard around CONFIG_MMC_SUNXI_SLOT.
The BOARD_SIZE_LIMIT applies regardless of ARM64 or not (now), so remove
that guard as well. The maximum number of MMC devices does not depend on
CONFIG_ENV_IS_IN_MMC, so move that out to simplify the file.
Last but not least CONFIG_SPL_BOARD_LOAD_IMAGE serves no real purpose
anymore: it's unconditionally defined for all sunxi boards, and protects
nothing applicable outside of sunxi code anymore. Just remove it.

When we added Allwinner SoC support to ARMv8, we needed to pull in an
implementation of lowlevel_init() calling the C function s_init(), as
sunxi required it as this time.
The last few patches got rid of this bogus requirement, and as sunxi was
still the only user, we can now remove this lowlevel_init.S from ARMv8
altogether.

Currently we do some magic "SRAM setup" MMIO writes in s_init(), copied
from the original BSP U-Boot. The comment speaks of this being required
before DRAM access gets enabled, but there is no indication that this
would actually be required that early.
Move this out of s_init(), into board_init_f(). Since this actually only
affects a very few older SoCs, the actual code goes into the cpu/armv7
directory, to move it out of the way for all other SoCs.
This also uses the opportunity to convert some #ifdefs over to the fancy
IS_ENABLED() macros used in actual C code.
We keep the s_init() stub around for now, since armv8's lowlevel_init
still relies on it.

According to their TRMs, Cortex ARMv7 CPUs with SMP support require the
ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB
maintenance operations are done. As we do those things still in start.S,
we need to move the SMPEN bit setting there, too.
This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR
very early in start.S, and moves sunxi boards over to use that instead
of the custom code we had in our board.c file (where it was called
technically too late).
In practice we got away with this so far, because at this point all the
other cores were still in reset, so any broadcasting would have been
ignored anyway. But it is architecturally cleaner to do it early, and
we move a core specific piece of code out of board.c.
This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few
years back, and moves the respective logic into the new Kconfig entry.

So far all Allwinner based boards were doing some not-so-lowlevel-setup
in lowlevel's s_init() routine.
This includes the initial clock, timer and pinmux setup, among other
things. This is clearly out of the "absolute bare minimum to get started"
scope that lowlevel_init.S suggests for this function.
Since we have an SPL, which is called right after s_init(), move those
calls to our board_init_f() function. As we overwrite this only for
the SPL, this has the added benefit of not doing this setup *again*
shortly afterwards, when running U-Boot proper.
This makes gpio_init() to be called from the SPL only, so pull this code
into a CONFIG_SPL_BUILD protected part to avoid build warnings.
